FE meshed models to be opened in 3D Slicer

I intend to use 3D Slicer to generate patient specific models from CT/MRI as input. I have a FE meshed model already created in LS DYNA which I want to morph so I don’t have to go through the model and mesh generating process again. Is there a way to open this meshed model in 3D Slicer?

Thanks and Regards,

Currently, Slicer can read volumetric meshes from VTK unstructured grid (.VTU) files only.

Probably the easiest for now is to load your LS-Dyna d3plot files to ParaView and from there save as .vtu file (see details here: https://www.paraview.org/Wiki/ParaView:FAQ).

If this additional conversion step disrupts your workflow then you can load the LS-Dyna file in Slicer using a few lines of Python code (reader=vtk.vtkLSDynaReader(), read the file, create a model node, and set the imported mesh as input).

Thanks Andras, I will give this a try!

Also as I am new to programming, could you let me know exactly where I should include the Python code in 3D Slicer?
