I am trying to do flow simulation with air traveling through a heated porous medium and then through an insulated tube. Dome shaped piece is porous medium, frustum and the tube are insulated. I built the pieces using revolve, and tried to run the flow simulation but SolidWorks gives an error "There is no solid in the project. Please check geometry or component control." I am fairly new to SolidWorks and don't know how to proceed.Would greatly appreciate any help.
