In the SOLIDWORKS® user interface, from the Tools menu, select COMSOL > Offline Synchronization to open the COMSOL Synchronize Offline window where you can save synchronization files that can be loaded by the LiveLink feature in a COMSOL model.

Before saving offline synchronizations files consider linking parameters for control from the COMSOL model, see The COMSOL Parameter Selection Window, and configuring selections on the geometry that can make it more efficient to define physics, see The COMSOL Selections Window.

From the Synchronization list select Initial (default) or Requested. If you select Initial the synchronization file will contain the current geometry. Select Requested to load a request file, and save a synchronization file with geometries generated for the parameter values in the request file.

Select to Synchronize material data together with the geometry. With this option the material properties defined in the synchronized part or assembly components are included in the synchronization file.

Select the type of objects to include in the synchronized geometry. Only the types of objects that are selected from the Solids, Surfaces, and Curves and points checkboxes are transferred during a synchronization. Performance can be improved for very large geometries that contain more than one type of objects, by turning off the synchronization of types of objects that are not necessary for the simulation. Note that you can also exclude selected objects from being synchronized by hiding them.

By default associativity is preserved for all entity types of the geometry. Turning off associativity for Vertices and Edges can improve performance when synchronizing very large geometries. To turn off associativity for an entity type clear the corresponding checkbox.

Click Browse to load a request file that was saved from a LiveLink feature in COMSOL Multiphysics. Once the file is loaded you can see information displayed about the requested document and the requested parameter values. Click one of the rows in the Parameters table to display a larger table. The fields in the Requested Value column will contain many values if the loaded request is for a parametric sweep, or if many requests have been saved in the request file. In the Current Value column you can see the values that the parameters currently have in the CAD model. An empty field in this column means that the corresponding parameter could not be found in the CAD model.

To generate a synchronization file according to the request do not change the default settings, that is, Synchronize with should be set to Requested document and Use parameter values should be set to Requested.

To generate a synchronization file for the currently active file in SOLIDWORKS choose Active document from the Synchronize with list. By setting Use parameter values to Current the synchronization file will contain the geometry built using the parameter values displayed in the Current Value column.

Click Save to save the synchronization file and close the window. This may take some time for parametric sweeps for which the geometry needs to be rebuilt many times.

For Initial synchronizations you can also click Append to add a synchronization to an already saved synchronization file. You can for example save a synchronization file, then manually change parameter values, rebuild the CAD model, then open this window again to append the new geometry to the previously saved file.

To close the window without saving click Cancel.
