I have a symetrical model, which is loaded symmetricaly and afterwards unsymmetricaly, therfore it is important to have a symmetric mesh.
Due to a strange geometry in the important region, tetraheder are more intelligent.
Is it possible to mesh a part with automesh and then mirrow this mesh?

Re: Mirrow mesh
It is technically possible to create half mesh and then create the other part by symmetry with the copy tool in mesh mode (with a mirror tranformation with the plane defined by 3 points) but this is not recommended. In general the rigth way is to create a geometry and mesh it without any manual mesh modification.
In fact when mirroring the elements the copy won't be exactly a mirror, because then the elements will become wrongly oriented (negative jacobians), the elements connectivities are automatically changed to become a 'valid element'
