Hi folks, I was wondering if you could help me with this problem ERROR: Splitting of existing meshes on a source face (face 59) is not implemented yet. Does anybody know how to solve this particular problem? Thank you so much in advance

what are you trying to do? hybrid mesh? or splitting your domain with interior to generate hex mesh. Or you might trying to mesh (with hex) a domain with either source is on splitted face and another one is single. It easy, just split the other face in the similar way (with the first one) then mesh them. I'm very sure this will work, because I have the same problem long time ago. regards, Jolius
