If users want to include CAD geometry not modeled with their flow simulation in CFD-Post, they can: 1) Create a coarse mesh on the solid geometry and import the .cmdb file(s) directly into CFD-Post. They don’t need to run the fluid solver on this solid geometry. 2.) Use the free app CAD2Post downloadable from the ANSYS App. You can use following link to download the app. https://appstore.ansys.com/shop/ACTApps_act%20apps
