Hi All,
I am dealing with an error I hadn't seen before and it seems to be unlisted.
My simulation consists in a 20cm long tube and 3cm diameter, at the moment I have a single particle running along the tube with periodic boundary. I used GMSH to create the geometry and mesh of the tube.
The simulation itself is simple, simple geometry, simple distribution, simple output. I run the simulation in serial first and I did not know what the problem was. Then I run it in parallel and I obtained a little bit more of information:
<>
According with this error the problem is in the stl file.
fix specimen all mesh/surface/stress file ../Geometry/internalFinishSpecimen.stl type 2 curvature 1e-5 stress on
I tried the command Heal auto_remove_duplicates, it did not work. I also tried exclusion list read and then write, it did not work.
I reinstall and compile LIGGGHTS again in case the problem were there and I had the same problem.
I have attached what is printed on the screen and not to the log file LIGGGHTS creates, I called them logerror*. I also attached the log files generated by LIGGGHTS and the geometry file.
The logerrors start with the following lines:

It carries on this way for a while.
Does anyone know what is going on? Can somebody point me in the right direction?
Best regards,
