Hi Derek,
Many thanks to your help, it’s going well. you are so friendly and professional.
But I also have some trouble, that is after I rewrite topography.vtk as topography.vts and topography.pvd successfully. I also can’t visualization topography by opening topography.pvd in Paraview. I don’t know how to deal with it.
Here is my output ./fastscape with topography.pvd, topography.vtk, topography.vts.
Looking forward to you.
