Hi Everyone,
I have problems while remeshing a mesh with periodic boundary conditions. I get an error when I reinterpolate fields on the new mesh.
The issue occurs with the file lgfem.cpp… but by looking at it, I am missing what it actually does.
Do you know what are the variables x0 and x1 ? I would like to understand this to understand the error I get,
I have an h quite small (h=0.005819), and a difference of xmx (=max(all x1,x0)?) - xmn (=min(all x0 x1)?) quite big (4.281e+04) and the ratio should not be too large if I trust the code; but in my case it is over 1e7 … 
If you have any indication, I would be glad!
Julien
PS: my error :
–Update: periodic 0 4.281e+04 h=0.005819
current line = 363
Assertion fail : (coef>1e-10 && (xmx-xmn)*coef < 1.e7)
line :1109, in file lgfem.cpp
PS2: the code states that 0 is xmn and 4.281e+04 is xmx
PS3 My mesh is also a sum of two meshes that are remeshed separetely, but I am not sure if this is relevant or not
