Errors in msh4 output - periodicity #418

Open mrkwjc opened 2 years ago

Hi!

I generated msh4 file like this:

neper -T -n 25 -dim 2 -periodicity 1
neper -M n25-id1.tess -per 1 -format msh4

but when reading the file with gmsh I obtained:

Info    : Reading 'n25-id1.msh4'...
Info    : 197 entities
Info    : 734 nodes
Info    : 1716 elements
Info    : Could not find periodic entity 7 of dimension 11
Info    : Could not find periodic entity 0 of dimension 1
Info    : Could not find periodic entity 0 of dimension 6
Info    : Could not find periodic node 0
Info    : Could not find periodic entity 0 of dimension 19
Info    : Could not find periodic node 0
Info    : Could not find periodic entity -1 of dimension 29
Info    : Could not find periodic node 0
Info    : Could not find periodic entity -1 of dimension 30

So it seems there are some errors in msh4 output. Or maybe am I doing something wrong?

I used neper-4.4.1 and gmsh-4.9.5.
