Warning: surface area for component 1 is zero

Hello!
I'm a newbie in Flow-3D and CFD in general. I'm trying to simulate a compressible supersonic air flow around a solid 3-D [almost] axisymmetric body. Despite that the Materialise Magics shows a non-zero surface area of the mesh (the STL-file), the Flow-3D preprocessor issues the warning "surface area for component 1 is zero". I tried this again with a simpler mesh but the result is the same. Perhaps that's why the simulation ends in just a couple of seconds with a zero result (nothing seen in the image but the coordinate system and a colour palette). I've assigned a material for the body but had I forgotten to assign a physical property for the surface so that Flow-3D considers it real? I'll be very grateful if experienced users can help me get the desired image of the oblique shock wave cone. The input and mesh files are at 4dos.hit.bg/flow-3d.zip Thank you very much for your help! |

One way to double check all that is to look at it in the GUI's Meshing&Geometry window. |
