      1. Perform inspections of the structure: self-intersections and free boundaries are not allowed.
      2. Make a solid of the structure.  
      3. Make the fluid domain based on points and create a box of it.
      4. Cut the domain with the structure.

  1. FMS file (best input for cfMesh) preparation 
  1. Open Salome and load in the CAD model with the fluid domain. (docs/solarPanel.brep)
