If you have licensed LiveLink™ for SOLIDWORKS®, the COMSOL Installer registers an add-in called the LiveLink for COMSOL (5.2a). This add-in should appear in the SOLIDWORKS user interface, listed in the Add-Ins dialog box, accessible from the Tools menu.
• In another mode you can work with COMSOL simulations inside SOLIDWORKS. This latter mode is called the One-Window interface. Only one version of the One-Window interface can be active at a time. If you have several COMSOL versions installed, make sure that the latest version of LiveLink for COMSOL is selected from the COMSOL>One-Window Version menu inside SOLIDWORKS. If required, restart SOLIDWORKS after changing the One-Window interface version.
