Error solvre
 

when i start the solver it give me this message ================================================== ==================== | Timestepping Information | ---------------------------------------------------------------------- | Timestep | RMS Courant Number | Max Courant Number | +----------------------+----------------------+----------------------+ | 1.0000E-01 | 0.00 | 0.00 | ---------------------------------------------------------------------- DOMAIN: Ingranaggio Reading mesh for map generation File read: C:\Mesh Deformabile\Meshes\Ingranaggio.0

Re: Error solvre
 

Check your mesh. You have some poor quality elements at location ( -0.10519E-02, 0.25736E-01, 0.47188E-02)

Consider improving your mesh quality first.
