Thanks a lot for the latest mmg version. The new metric gradation is improving a lot the quality of my elements close to a required entity and it accelerates the algorithm convergence for a very fine metric.
At this moment, I encounter some problems with the 3d features, when I wish to freeze some internal faces or edges.
Please find in the attachment two of my scenarios.
• The first one only requires two triangles and two edges, and no other entity. In this case the tags are completely lost.
• The second one requires two triangles and two edges, which exists at the intersection of 2 or 4 tagged subdomains. In this case the output contains the required triangles and their associated tags, but it looses the edges.
Do you have some hints that could fix this issue?
Note that I am usually using the C interface for remeshing, but, in these examples the same results are obtained by the equivalent command :
mmg3d_O3 input1.mesh -sol input1.sol -hgrad 1.25 -hausd 0.05 -hmin 0.1 -hmax 1.0 -v 5
