Quick answer: looks like it did work until version 3.5.1... Not sure why this has got broken.

I encountered the same problem while using neper.
I encountered the same bug in version 4.2.1-35. Is it something that it is expected to be fixed soon @rquey ?
Quick answer: looks like it did work until version 3.5.1... Not sure why this has got broken. (...)
Regarding neper 3.5.1
, an error occurs while compiling the code (I pasted a picture because it has colour highlighting the errors):
neper 3.5.2
is compilable but the error related with periodic and cohesive elements is already present in that version.
Version 3.5.1 compiles fine on my system (despite some warnings). I have
$ gcc --version
gcc (Ubuntu 9.4.0-1ubuntu1~20.04.1) 9.4.0
I have exactly the same compiler version but the previously mentioned errors still occur. There are some undeclared variables. Even if those are deleted, other problems appear around the 70% mark.
The commit hash is f4ecbfc
.
Hmm... Not sure what happened to these commits. v3.4.0 works (4fd71846ce72035a80e32f92ca41dcf5f602a4e2).
Thank you @rquey! In version v3.4.0 the creation of periodic tesselations and meshes is working for 2D RVEs. Unfortunately, the meshing module outputs an error in the "Making mesh discontinuous..." (or in "Adding cohesive elements...") phase for 3D RVEs.

Hi @rquey
I have installed version 4.5.0
and periodic tesselations with cohesive interfaces are not working both for 2D and 3D meshes. The same occurs for -order 1
ou 2
.

Just out of curiosity, are you planning on working on this any time soon?
Does periodicity not work with cohesive interfaces?
