I am trying to use mmg2d to adat a mesh, adn I’d like the cell size variations to be small along the boundaries. For this purpose, I use a value of hgrad = 1.1, but I end up with significant variations of the cell size at the boundary. An exemple is available here:
The edge sizes along the profile are:
In this case I get a stretching of up to 20%; but in some cases it goes upto 50%.
Is it possible to force the stretching to be smaller at the boundaries than inside the domain?
Thank you very much for your help.
