Hi, I have expert the data in the format of VTK, but after the simulation, i suddenly found that i have forgot one parameter to select in the VTK setting to write, can i have some method to add this parameter in the VTK and avoid to simulate this project again? Thank you very much!
Unless the missing variable can be computed directly from existing vtk variables (say particle volume if you have the diameter), I am afraid this is not possible. If you can compute the new variable based on existing variables, you will need to use Paraview and apply a Calculator filter.
