Wrong mesh dimension: -1!

[enghorbani]

hello every one

Could you please help me to solve this error?
I made a 3D spherical particle in Neper and I tried to mesh it with tetrahedral element but I got the following error:

root@DESKTOP-OF0TB9H:/mnt/c/users/work15/desktop/Practic/M2/M3/M4/F1# export OMP_NUM_THREADS=1

Did you run the tests after installing Neper? Looks like a Gmsh issue. How did you install it?

I followed the Installing Neper structure based on Neper website. I had many challenges to install it. When I installed Neper I ran neper in Ubunto and got this messeage:

What should I do now? Could you please help me?

Please use markdown formatting for your message (on the top right of your above message click ... then Edit to see how I did it).

From the build folder, run ctest to run the tests.

[enghorbani]

Thank you for your support.

You mean In the build folder I just click on the CTestTestfile.cmake?

[rquey]

Please follow the instructions from the manual for installation and testing: https://neper.info/doc/introduction.html#installing-neper

When you are in the build folder (in the terminal), run the command ctest.

Anyway, I think your Gmsh is not properly installed.

Thank you so much

In the -M module, the -elttype field cannot be omitted. Otherwise, Wrong mesh dimension: -1!
