Sharing a Model Between Excel® and the COMSOL Desktop®
You can share a model that is open in Excel with COMSOL Desktop by connecting COMSOL Desktop to the same COMSOL Multiphysics server as Excel is connected to. This makes it possible to access the model settings simultaneously from Excel and from COMSOL desktop.
LiveLink™ for Excel® connects Excel with a COMSOL Multiphysics server, started in graphics mode. This is called a graphics server. The graphics server does not support multiple clients connected at the same time. To share a model between the COMSOL Desktop and Excel you need to start a regular COMSOL Multiphysics server when opening the model in Excel. See Preference Settings to set the connection between Excel and a COMSOL Multiphysics server without graphics.
