Dear all,

I found in sometimes the adaptmesh will not give the same results. The mesh adapted with the same adaptfields and options may be a little different in the number of vertices ( although not big difference , like vertices number of 80000 and 80010)… could we figure out a way to get the deterministic results (I think it might be better)?

Thanks a lot~
