When I try to synchronize the geometry between COMSOL and PTC Creo Parametric, the error message
Failed to connect to PTC Creo Parametric. Please make sure PTC Creo Parametric is running.
is displayed, and the COMSOL Multiphysics tab in PTC Creo Parametric is not available.
If you have licensed LiveLink for PTC Creo Parametric, the COMSOL Installer creates an add-in in PTC Creo Parametric called LiveLink for COMSOL (5.5). This add-in should appear in the PTC Creo Parametric user interface, listed in the Auxiliary Applications dialog box, accessible from the Tools tab. For older versions of COMSOL Multiphysics, the version number will be reflected in the name of the add-in.
The connection between COMSOL and PTC Creo Parametric can fail if the add-in cannot be loaded by PTC Creo Parametric. Problems that might result in this error are that PTC Creo Parametric is installed after the COMSOL installation, PTC Creo Parametric is updated or installed in location different from the one specified during the COMSOL installation, or that the COMSOL installation is moved.
To fix this issue, it is possible to reinstall LiveLink for PTC Creo Parametric, or to repair the installation as described in knowledgebase 1221, or to set up the connection manually as detailed here.
