Mirrow mesh

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?

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'
