I am trying use an imported STL file of blood vessels to perform some fluid dynamics simulation. To close off the ends to create the fluid domain inside the vessels, I think the best way is to use the Cap Faces feature in CAD import module.
When I try to use this feature (choosing the loop defining the perimeter of the vessel cross section) - it just gives me an error "Operation not supported on virtual geometry".
Not sure what this means - please let me know if you know a solution.
