Hi Jesse, Usually vtkMultiBlockDataSet is used so as to store multi-body datasets and the corresponding file format is a VTK vtkMultiBlockDataSet format (.vtm). But in time development model such as your case, you'd better use a ParaView Data format (.pvd) because vtm can't handle time information. I attach the pvd file sample.
I also think the Multiblock Inspector is very convenient in multiblock processing. https://blog.kitware.com/upgrades-to-the-multiblock-inspector/ Thanks, 2017-06-07 1:22 GMT+09:00 Jesse Gerber <[email protected]>: > Hello, > > I am a mechanical engineering grad student.
