vtu files visualization

Postby simonz » Sat Feb 13, 2016 4:04 am

Hi:
I've done the preprocessing for my simulation, and when i trying to import the vtk files which are generated after the calculation process, the GiD shows a warning as: GiD_MeshPost: bad element number of nodes '10'. Quadratic elements are not implemented.
The vtu files are attached and i really appreciate if anyone can have a look and tell me what should i do in order to complete the post process.

Thank you so much for your help~

The import of this VTK mesh+results files fail because now is only possible to import meshes of linear degree, and the example has quadratic tetrahedra of 10 nodes.

GiD itself support this kind of quadratic tetrahedra in pre and post, but nowadays the VTK import plugin is limited to linear degree elements (because is using the GiD-tcl command 'GiD_MeshPost' to create the mesh and now this command has this limitation)

We expect to overcome the related limit for future GiD versions, until now maybe you could do you simulation with linear tetrahedra of 4 nodes.
