Blood Vessel Flow with STL format

I want to simulate an incompressible flow inside the blood vessel. The 3D geometry of vessel wall was reconstructed from medical image using other software and available in STL format. Which product can I use to run the simulation? Will the Panel Flow add-on be enough?

STL no good for Internal Flow

Sorry you won't be able to simulate internal flow with STL in Caedium. Topologically STL is a sphere, so you won't have the inlets, outlets, and walls groupings necessary to apply boundary conditions.
