I am running a code on many hundred cores. When I use inbuilt fenics mesh, everything runs fine. When I use Gmsh, I get the following error after the code runs for 50 - 60 time steps.
Please share you suggestions on what this means and how to get rid of it.
Error: Unable to clear VTK file.
*** Reason: Unable to open file "Results/pDP1_p521_000034.vtu".
*** Where: This error was encountered inside VTKFile.cpp.
The code is in C++, and I am now making an attempt to run a code which writes xdmf instead of pvd. But then, even if that works, I will face this problem, which I don't know how to get rid of.
