Hello, I propose to add the functionality to export results to \*.vtu format in order to be able to analyze the data in Paraview.

Cheers and keep going with this great Software.

Thank you for the idea, but I think there are existing tools that convert result .frd files to Paraview files. That is why this feature is very low on the to-do list.

A converter for .frd to Paraview vtk/vtu can be found here:  
[https://github.com/calculix/ccx2paraview](https://github.com/calculix/ccx2paraview)

A patch for older versions (2.17) of the Calculix solver ccx exists which allows result export in exo file format (ExodusII, can be be viewed in Paraview).

add an ‘exo’ argument to the PrePoMax menus could be useful.

Have tested several conversors, and the best to me is CalMED, that export to RMED format that can be readed by the version of Paraview downloaded from the page of Code\_Aster for Windows.

Looks a little complex, but this conversor/format puts all the results in a single file, so is quiker than reading several ones in case of doing no lineal analisis (also quicker for the conversion). Also it convert all the variables in the .frd file. For example I had a lot of troubles to make an animation of a plastic analisis using a set of vtk results, but can be easily done with RMED results, and there are other problems that I don´t rememeber now, but they exist in the vtk/vtu exported results.
