COMSOL Multiphysics is a great software for solving computational fluid dynamics (CFD) problems. When we import geometries from other software packages such as AutoCAD or SolidWorks, it requires a special license called the CAD module, but that module requires a separate license and for our shared licence system at the university, sometimes it is not available.
Today I’m going to present a work-around to decrease your dependence on the CAD module, as was discovered by our group member Colby Cash. Hope you’ll find this useful.
- I need to point out that when you first import the geometries into your model, you have to make sure the CAD module is available because at this point you are still importing a CAD file. So go ahead and do it.
- Next, go to Geometry, and select the Export button shown below.
3. Now you will see the following, and choose a place to export your geometry. Here let’s name it “Geometry to be exported”. Make sure the File type is “.mphbin”.
4. Now open a new model, add a new geometry and import the new file we just created as below. This time, and every time you open the model in the future, you will not need to use the CAD module license.
