I'm trying to visualize FEM data with cell type 25 (Quadratic_Hexahedron). Visualizing displacements with Hedgehogs works fine. However when trying WarpVector vtk crashed, and the same happens when running the attached tcl script e1.tcl, a much simplified version of the example in page 100 of vtk4.2 User's Guide. The code works fine with blow.vtk but a memory violation occurs with my data, Funcho_Desloc_vtk.vtk I include also the hedgehog code. I'm using vtk 4.2 with tcl 8.3.2. I can supply the data file (248kb) if anyone is interested, Regards João Cunha
