In PTC Creo Parametric™, right-click a feature in the model tree, then select COMSOL Parameter Selection to open the window with the same name. Parameters for the selection are displayed in the upper table, Feature parameters. Click the Change Selection button to select a different feature. Select the feature from the model tree, then click OK in the Select window to return to the COMSOL Parameter Selection window. Select parameters from the Feature parameters table, then click the Add button to link them to COMSOL. Linked parameters are listed in the lower table, Parameters to add to COMSOL model. All types of parameters can be selected, but only parameters that are not locked or driven by a relation are possible to control from a COMSOL model. Linking parameters that are locked or relation driven enables using their values in COMSOL model definitions.

Parameters listed in the Parameters to add to COMSOL model table will be saved in the PTC Creo Parametric™ file next time you save the file. To remove saved parameters from the file clear the table first and then save the file. Click the Revert to Saved button to reload the parameters from the saved PTC Creo Parametric™ file. Confirm your changes by clicking the OK button.

For additional information about parameters in CAD files see the PTC Creo Parametric™ documentation.
