I have a d3plot output file from LS-DYNA.  
I can load this d3plot into paraview.

 ![image](https://discourse.paraview.org/uploads/default/original/2X/6/6e6eb03c5be614d3a7f3861119c9e0cc91510a79.png)  
As you can see paraview creates a Multi-block Dataset to represent the d3plot.  
Under this multi-block Dataset, this is one part called car1-body-shell which is stored in an unstructured grid.  
I was wondering if there is a way to extract this car1-body-shell and save it to vtk unstructured grid format?

Any suggestions would be appreciated.  
Thank you!
