I read in the uvn file generated by salome mesh with gridin. But it gives me the following error . Attachment please find the unv file. I couldn't find what caused the error.

terminate called after throwing an instance of 'dealii::StandardExceptions::ExcIO'
  what():
--------------------------------------------------------
An error occurred in line <864> of file </home/ztdep/Downloads/dealii-9.4.0/source/grid/grid_in.cc> in function    void dealii::GridIn<dim, spacedim>::read_unv(std::istream&) [with int dim = 2; int spacedim = 2; std::istream = std::basic_istream<char>]
The violated condition was:
    in.fail() == false

UNV is a terrible file format. It is, in essence, a memory dump of a program that was written many decades ago. It is a disaster to parse because there are so many things that can appear in these files.

Can you let SALOME export the mesh in any other format?
