In Solid Edge®, open the COMSOL Parameter Selection window by clicking the Parameters button () located on the COMSOL Multiphysics tab. The window lists all dimensions and variables for the active part or assembly. To link a parameter to COMSOL select the corresponding checkbox in the Add to COMSOL Model column. All types of parameters can be selected, but only parameters that are not defined by a formula are possible to control from a COMSOL model. Linking parameters that are defined by a formula enables using their values in COMSOL model definitions.

The list of linked parameters will be saved automatically in the Solid Edge® file the next time you save the file. To reload the list of linked parameters from the saved file click the Revert to Saved button.

Note that to select dimensions from a part inside an assembly, you need to make the part active in Solid Edge® before opening the COMSOL Parameter Selection window. Remember to return to the top assembly before synchronizing.

For additional information about dimensions and variables in CAD files see the Solid Edge® documentation.
