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,  
Harish R Rao

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](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?
