PS: not sure if the solution was posted to the list. Basically, if "element size * Mesh.RandomFactor" approaches machine accuracy, you should increase the value of Mesh.RandomFactor. On the command line, use e.g. "-rand 1.e-8". > > CREVOISIER David wrote: >> >> Good afternoon, >> >> >> >> First, congratulations for the development of Gmsh, this tool has a >> lot a great qualities. >> >> >> >> I try to mesh several very thin surfaces, structured in a network of >> cracks.
