Problem reading mesh when in MPI version

How do I read a generated mesh in the MPI version? The documentation doesn’t talk about this…

I use the command below to read the mesh. Normally it works fine. However, in MPI version, I encounter this error message.

mesh Th = readmesh(“ThCoarse.msh”);

mshptg bug in number of points 0 > 0 == max nb points
Error mesh generation in mshptg : err = 1 nb triangles = 0
current line = 237 mpirank 0 / 1
Assertion fail : (err==0 && nbt !=0)
line :1768, in file …/femlib/fem.cpp
Assertion fail : (err==0 && nbt !=0)
line :1768, in file …/femlib/fem.cpp
err code 6 , mpirank 0

ThCoarse.msh.edp (3.2 MB) (i added .edp because .msh is not allowed…)
