Dear all,
 
I'm having some difficulties having converged results on some simulations and I would like to take advantage of the various mesh quality tests performed during the CheckMesh procedure to check my meshes.
Where can I found the definition of the different criterion and their target good value or acceptable range ?
I'm talking about the following criterion (those avalaible for graphic post/processing):
-Face_Warp_c_max.
-Grad_RC
-Weighting_C_max
-Offset_c_max
-Non_ortho_c_max
-Error_Grad_RC
-Grad_LSQ/Grad_LSQ_Ext/Grad_LSQ_RC/Grad_LSQ_ExtRed
Some criterion seem clearly related to geometric cell characterics other are not easily understandable.
Any help would be great.
Thanks in advance

Dear Julien,
 
The really interesting criteria output from the check_mesh procedure  are the non orthogonality and the weighting. Non orthogonality should ideally be lower than 65° and weighting have to be visually smooth.
Others criteria are informative (it's very difficult to give an ideal range) and will be describe in a coming documentation.
