Dear all, 2 or 3 years ago, I coded a simple interface to the commercial finite element code ANSYS. It was working fine at that time. Mainly, it is a simple python interface which generates an ASCII *.vtk file in the legacy format, version 2.0.
I tried to use the same interface tonight and with the latest version I can open the file, but if I click apply, paraview aborts with the following message. *** Error in `/home/utabak/external_programs/ParaView-5.2.0-Qt4-OpenGL2-MPI-Linux-64bit/lib/paraview-5.2/paraview': free(): invalid next size (normal): 0x0000000003255440 *** Aborted (core dumped) I tried on a simpler domain to debug a bit, but the input file seems fine to me. Moreover, I can open the same vtk file in another open source mesh generator, which is quite popular, namely, Gmsh without any errors. So I am wondering the reason for this problem. I also attached the input vtk file for your reference. Any help is appreciated. BR, Umut
