I have attached a part file created form an assembly. I am wanting to conduct a flow test with rotation. I cannot figure out how to sketch and extrude the rotational region as I cannot extrude it and chose not to merge the extrusion results. Any ideas?
Hi Karn,
The main problem I see in this file is that you have only a large number of surface bodies and no solid bodies. I might expect to see this if you had saved an assembly into a part file using the 'Geometry to save' option set to "Exterior faces". Surfaces won't work for Flow Simulation so you would first want to rectify that by re-saving the assembly with 'Geometry to save' set to "All components" like you see below:
Once you have a file full of solid bodies then you will find that your extrusion has the 'Merge result' option to turn off.
