[Paraview] d3plot transform to vtk file

[David Thompson]

Hi Yusuke,

I'm not sure what you mean by "central axis". Do you mean the central axis of the simulation or the middle layer of a thick shell element? If the latter, note that the LS-DYNA file format only stores fluid pressure information at nodes or on SPH particles. If the shell elements do not have nodes on their middle layer, then no pressure information is available there and you will have to interpolate it.

Also, are you sure the pressure variable is being saved in the d3plot file? LS-DYNA may be configured to save pressure or not. 

Finally, there are other files (the time history database: d3thdt; the interface force database: intfor) that VTK's LS-DYNA does not support but that LS-PrePost is able to read. If the pressure information you want is stored in these files, VTK will not be able to read it.
