Different OS different mesh
I have been using gmsh 4.7.1 on a linux system (ubuntu 20.04) and a mac laptop (Mac OS 10.15.7) with a common python script on both machines. It turns out that the meshes created via the two machines have different numbers of nodes and elements. Is this an expected behaviour? Should I get two identical meshes?
There are a couple of differences between my two machines:
- The mac is running python 3.9.0 whereas the linux machine is running python 3.8.5
- The gmsh build for the mac uses petsc 3.9.3 and linux build is using version 3.10.2
If this is unexpected behaviour, then I will attach my python script and the associated input data (they are quite karge).
Also, the mac version appears somewhat unstable. The gui crashes often and sometimes the "tools" windows (eg "options" and "visibility") change size within their larger "shell" windows for no apparent reason. They also change back to normal at random. I can upload some screen shot if necessary.
Thanks very much,
