Hello,

I try to improve my mesh quality Orthogonality, I have 36 failed min Orthogonality,

despite a Mesh> Check > Elements > Solid Mesh Optimization,

 

it still 36 failed Min orthogonality

 

Did anyone have a solution to solve it?

 

Regards!

    Hello,

    Try find attached tetras and then remesh the patches.

    Did you try Simlab? I heard it generates higher quality tetra models.

    Hi,

    Thanks for you answers. 

    Finally I changed my computational algorithm  in my volume meshing (with the advices of Altair support! )

    I process with the following pannels :

     it is the tetramesh parameters (with the Optimize Mesh quality define with the User Controlled) and (the tet collapse to 0.800) which allows to generate mesh without failling elements!

     

    Thanks again.

     

    Regards!

    Note : A process to improve mesh when it is done can be use on the Mesh > Check > Elements > Solid Mesh Optimization (with edit criteria to fix ortogonality : 16 case to coch) then fix max iteration (10) and click on Fix...
