Hello,

Sorry to bother, I've got a question regarding cgns:

I've created a (volume) mesh by extruding a surface mesh along a curve. In order to do so I had to convert the 2D surface block to unstructured. The problem is that I want a structured cgns output. I've tried first converting the 2D surface mesh to multiblock but then I can not extrude the surface mesh.

The workaround would be to create the mesh by using a 3D block but I can not get a good quality mesh that way. My geometry is a 3D 90 degree pipe bend. I've completed a very similar tutorial (hexa mesh generation for an elbow part) but it is very difficult to set the correct associations in order to get a good quality mesh in my case.

What would be your suggestion to cope with this problem?

Thanks in advance

Please post some images so that everyone can visualise the problem and whether it is some obvious problem with the geometry or blocking.

Thanks.

Edit: I already solved this problem. As I said before I needed a 3D block in order to export the mesh as a structured file. I've found the correct 3D blocking strategy.

Thanks
