Hello Everyone,

I have used the option Import-GiD Mesh to import a mesh in preprocess.
I tryed to generate a new mesh on the imported mesh, but got an error and no mesh was generated.
I tryed to use Import-Mesh Surface, and did change size of elements, but when opened the new mesh file in postprocess the 'old' mesh (before new generation) was opened.

1. Can I change not only the size of elements in Impoer-Surface Mesh, but also type of elements etc. ?
2. Why did I get the error in Import-GiD Mesh ?

Thanks a lot,
Dganit

If you have a mesh (created or imported), and try to re-mesh, then the old mesh is deleted, and is generated
a new mesh from the geometric entities (points, lines, surfaces or volumes) .
In your case maybe not exists any geometric entity.

If you want to re-mesh a previous mesh, and don´t have the related geometric model, can try to import as "surface mesh".
This create a "pseudo-geometric" entity (based on the mesh shape). You can try to generate a mesh from this entity, but
it only works for simple cases. After generate the mesh, it's automatically transferred to postprocess, it's not necessary
to save it (in a GiD Mesh Ascii file) and reopen in postprocess.

Hello Enrique,

Thanks for your reply.
I re-meshed an imported "surface mesh" and toggled to postprocess as you have recomended. But the postprocess opened the old mesh and not the new generated one.

Please help,
Dganit

Maybe you have a mesh file named for example "yourmodel".flavia.msh
then this external mesh file, if exists, it replace the internal mesh when toggle to postprocess.

Rename this file or the model.
