nofem option ?

[GSS79]

i've been looking at the nofem option but it is not clear to me what is the default behaviour of MMG if nothing is done regarding this.

As i understand, nofem controls the fact that MMG splits elements that have multiple faces in different boundaries ( avoiding for example a single element to be a full corner element ).

But i have tried
MMG3D_Set_iparameter(mmgMesh, mmgSol, MMG3D_IPARAM_nofem, value);
with value 0 or 1 and dont see a change in my case.

if MMG3D_IPARAM_nofem is not specified what is the current behaviour ? Spitting the element or leaving as is ?

in fact this option handles surface splitting in 2d and element splitting in 3D. In 3d the bnd surface are not split. An adhoc version was created to split the surfaces of the 3d element if all nodes of a surface are bnd but it is hard code : feature/split-nonrid-edg-connecting-rid-pts
