This will add a new isovolume to the model. The isovolume will be assigned an id by the model.
The default settings are:
Returns the new Isovolume.
Adds a one-shot callback that will be called once the next server visualization update is complete.
Whenever you change something in a RemoteModel, the pending changes will immediately be registered client-side, but will not be dispatched to the remote server until later. This server update typically happens in response to requestAnimationFrame() processing. The callback registered by this function will only be triggered once the next server update has been dispatched and has completed.
Please note that the callback will only be called once.
Adds a ParticleTraceGroup to the remote model.
This will add a new particle trace group to the model. The group will be assigned an id by the model.
Returns the new ParticleTraceGroup.
Append the model with the given model key to the current model opened with openModel()
The models needs to be compatible. The requrement is that they have the same number of geometries and parts (i.e. same total number of parts).
This is useful if the simulation results are split into multiple runs, e.g. if the simulation was stopped and then continued with the same model but computing new time steps / increments.
DEPRECATED. Will method will be removed in EnvisionWeb version 3.1
Apply the VTFx case with the given id to the model.

This might be faster or slower than a server pick request, depending on model size, latency, server capabilities and client capabilities. Note that this picking only considers visible surface geometry.
If something was hit, returns a ClientSideHitItem object containing information about the hit. Returns null if nothing was hit
Closes the model, cleaning up on both the server and the client.
Create a new result calculator result based on the given specification.

Opens the model with the given modelKey in this RemoteModel.
Opens a model on the server and prepares to stream it to the client. If the model is opened successfully (as indicated when the optional callback is invoked) the initial step of the CAE model will be streamed to the client.
The identifier of the model to open. This will be translated on the server into a filename before the model is opened. This translation is done by the modelFileFromKey() function that is provided to createServerInstance() on the visualization server.
Callback function that will be called when the model is ready to be used in the client. This will also be called if any errors occur (file not found etc.). When this is called the ModelDirectory will have been populated with the contents of the server CAE analysis.
Open model options. Provide any default calculators and/or an internal configString. See OpenModelOptions for more info.
Example: Customize the initial appearance of the model in the callback:
// Remove any old models
var view = myViewer.getViewAt(0);
view.removeAllModels();
// Open a new RemoteModel from the CAE server
var mySocket = io('http://localhost:8998', {reconnection:false});
myModel = new cee.ug.RemoteModel(mySocket, "");
view.addModel(myModel);
// Open the file on the server, setup the viz when it is done

// Modify the part settings: First part transparent, the rest with surf mesh
for (var ps of model.getPartSettingsArray()) {
ps.drawStyle = cee.ug.DrawStyle.SURFACE_OUTLINE_MESH;
ps.opacity = 0.5;
}
});

Poll the current data source for changes.
Note: Only one poll can be in flight at any given time, so calling this method while a poll is being processed will throw. To make sure you do not do that, use the isPollForDataSourceChangesInProgress method to check for any ongoing polls.
Performs picking on the remote server model.
This will perform a picking action on the remote server with the given ray. The provided callback will be called when the result is available. The hitItem provided to this callback will contain detailed information about the element that was hit in the CAE model.
To do the picking at the current state/time step, use the model.currentFrameIndex property.
Recreate the result with the given calculatorId and resultIdString.
Use this method to update an already existing calculator result. From the client side it will seem like the result is just updated with the new initString, but on the server the actual calculator instance will be deleted and a new one will be initialized with the given initString.
The result will keep its id (number) so no updates are needed to the model spec or feature extraction items.
Reload model, pick up any changes on the server since the open of the analysis.
Share the model on the web using the Ceetron One-Click-Sharing service.
With this method you can share the remote model (with the current settings) to the Ceetron Cloud cloud service.
You can either use the default https://cloud.ceetron.com service, or use your own hosted sharing portal. The Ceetron Cloud Portal can be customized and installed on most cloud and on-premises servers.
Set the title of the color legend with the given result Id
This will update any current legends, and also be used as the title whenever the legend is later created.
Sets a handler function that will be called with information about the current communication.
See CommunicationPerformanceData for more information.
Sets the draw style for all parts in the model
This is just a helper for setting PartSettings.drawStyle for all parts in the model, and optionally set opacity if provided.
Sets a one- shot callback that will be called the next time we observe that data streaming is complete
Sets a handler function that will be called whenever a progress indication packet is received from the visualization server.
Set options for the reader with the given readerIdString
The options will be sent to the server and used whenever a file of the given type is opened.
Available options:
VTK (vtu/pvtu): readerIdString: "VTK"
OpenFoamProvider: See the readme file for the provider.
Example:
this.m_model.setReaderOptions("OpenFoamProvider", {
"LOAD_BC_PARTS": true,
"NODE_AVG_RES": true,
"HIDE_PARALLEL_INTERFACES": false,
"UPDATE_GEOMETRY_FOR_AMI": false
});
this.m_model.setReaderOptions("VTK", {
"ALL_VECTORS_AS_DISPLACEMENT": true,
});
Sets result calculator parameters for the given result calculator result.
The result will automatically be updated.
Example:
model.setResultCalculatorParams(calcId, resIdString, { "scaleFactor" : 2.0 });
Specifies the handler function that will be called whenever any result changes in the model. This will be called when a result is loaded the first time or when changing time step.
This might be useful for updating the UI, e.g. the minimum and maximum values on a slider for an isosurface.
Sets a handler function that will be called whenever an error packet is received from the visualization server.
Set an array of key,value pairs that will be included as a context in the server log.
This key,value pairs will be available in the JSON type log, and will be included until a new key,value array is specified. To clear any current settings, pass in an empty array.
This could be used to enhance the telemetry support in your cloud solution.
Start the streaming of the initial 3d model from the server.
Note: Calling this method is only needed when using the openCompletedCallback parameter to OpenModel and returning POSTPONE_STREAMING.
Static method to get custom server info from the UgServer.
This info is specified on the server in the createServerInstance() method or the constructor to ServerInstance.
Default response is null.
Generated using TypeDoc
A remote server CAE model that can be displayed in the client viewer.
The RemoteModel is the controller of the visualization of the CAE model. Using this class you can specify which results to show on the model, set part settings as well as create cutting planes, isosurfaces, isovolumes and particle traces.
Use openModel to open a CAE model residing on the server. Once the optional callback passed to openModel is called, the ModelDirectory will have been populated and you can configure the initial view of the model. If a callback is not provided to openModel then the first state is shown.
Example: Minimal app, open default model on server:
var mySocket = io('http://localhost:8998', {reconnection:false}); var canvas = document.getElementById("myGlCanvas"); mySession = new cee.CloudSession(); myViewer = mySession.addViewer(canvas); if (!myViewer) { return alert("No WebGL support"); } myModel = new cee.ug.RemoteModel(mySocket); var myView = myViewer.addView(); myView.addModel(myModel); myModel.openModel(""); function myAnimationFrameCallback(highResTimestamp) { mySession.handleAnimationFrameCallback(highResTimestamp); requestAnimationFrame(myAnimationFrameCallback); } requestAnimationFrame(myAnimationFrameCallback);
The ModelSpec is the object you use to specify what to show in the remote model. Here you set which state(s) and results (scalar, vector, displacements) to display. You can setup a state animation by setting ModelSpec.stateIdArray, or setup a mode shape animation with ModelSpec.modeShapeFrameCount and ModelSpec.modeShapeAnimationType. Animation is controlled by the Animation class which can be accessed with animation.
You can access PartSettings objects with getPartSettingsById and use them to set various part attributes such visibility, color, opacity and draw style.
You can control how results are rendered with ScalarSettings, VectorSettings and DisplacementSettings objects, which can be accessed with getScalarSettingsById, getVectorSettingsById and getDisplacementSettingsById respectively.
For volumetric models, you can add any number of cutting plane, isosurface, isovolume and particle trace group objects to gain insight into the result distribution (e.g. flow field) within the model. The settings of these items can be controlled with the CuttingPlane, Isosurface, Isovolume, and ParticleTraceGroup objects. Use getCuttingPlaneById, getIsosurfaceById, getIsovolumeById and getParticleTraceGroupById to access such objects.
Picking is also done in the RemoteModel. Use rayIntersect to perform picking on the remote server model. This method takes a callback which is called when the picking result is available.
See the example in Examples/BuildYourFirstApp/3-FirstPostProcessor and 4-FeatureExtraction for how to use the RemoteModel
Example: Show the last state with the first scalar result and modify part settings
// Get the model and the model directory from the RemoteModel var modelDir = myModel.modelDirectory; // Show the last state in the analysis var modelSpec = myModel.modelSpec; modelSpec.stateIdArray = [modelDir.stateInfoArray[modelDir.stateInfoArray.length - 1].id]; // Show the first scalar as filled contours (if any) if (modelDir.scalarResultArray.length > 0) { modelSpec.fringesResultId = modelDir.scalarResultArray[0].id; } // Modify the part settings: First part transparent, the rest with element mesh for (var i = 0; i < myModel.partCount; ++i) { var partSettings = myModel.getPartSettingsAt(i); if (i == 0) { partSettings.drawStyle = cee.ug.DrawStyle.SURFACE; partSettings.opacity = 0.5; } else { partSettings.drawStyle = cee.ug.DrawStyle.SURFACE_MESH; } }
