How to Create 2D Models from 3D Geometries

Learn how to create 2D models from 3D geometries in COMSOL Multiphysics with the Cross Section feature, available with version . By taking cross sections of 3D CAD models, you can run fast what-if studies in 2D to save time and computer memory. Step-by-step, we walk you through how to create a cross section from a Work Plane in a 3D model, adding a 2D model, then using the cross section as the 2D geometry. The Shell-and-Tube Heat Exchanger model shown in the video can be found in our Model Gallery: htt
