Hi all,

I am trying to mesh an aerodynamic domain, where one smaller cube is inside of another bigger and which symmetry surfaces are in the same plane (one contents the other). I need a really fine mesh close to the walls of my object (the smaller cube) and coarser far away from it. In order to achieve that, and taking into account that my PC is not good enough to do that in one step, I am trying to do two separate tet meshes. After I got it, I merge them, selecting the common surfaces and frozen the inside mesh. When this is done and I checked the mesh I got some problems in the vertice where the symmetry surfaces are in contact.

I have tried to merge nodes but that doent work. Does anyone have an idea of what can I do?

I apreciate any help you can give me

Thank you
