Re: Long CPU time in gradients reconstruction

Dear Yvan,

here is a hopefully accurate comparison of the situation. The mesh is a tetrahedral mesh produced with SMESH, with maximum aspect ratio of 8:

- Extrapolation:
- Least squares with extended neighbourhood: 12 secs
- Iterative: 9 secs
- Least squares: immediate divergence

- Neumann ...

Long CPU time in gradients reconstruction

Dear all,

When I perform CFD calculations, I double check my results by using both code_saturne and OpenFOAM.

Considering the same geometry and approximately the same number of cells, on the one hand, code_saturne performs slightly better in the resolution of the linear systems, but a lot of ...
