WARNING: INCOMPLETE MESH: the software did not have enough memory to generate the mesh, thus the final mesh is probably not satured in term of number of nodes. However, the final mesh is valid so you can rerun Mmg3d beginning with this final mesh by increasing the memory (-m 500 for instance).
NB :In this case, the final mesh is correct (in sense of conformity) even if it is not well adapted to the prescribed metric.
