Q) I need to mesh a thin geometry to do some 2D rectangular laminar studies (driven cavity). I have tried to create some inflations along all the direction to improve my solution; I would like to divide my geometry in Cubes or Hexahedrals. Is it possible to do that in CFX Mesh 8.1, how can I create a 2D mesh?
A) We do not have a hex meshing tool within the CFX ' Mesher, nor is it possible to do a true 2D mesh. We have a pseudo 2D meshing tool (1 cell thick). To create one what you need to do is the following:
1) Under the Mesh branch in the display tree click on Options. In the detail panel you will see the Meshing strategy, in the pull down box change it to Extruded 2D Mesh.
2) You will now see the entry Extruded Periodic Pair under the Mesh branch ' This will have a red warning symbol next to it. Click on the Extruded Periodic Pair branch, and in the detail panel, fill in the surfaces(s) that form the 'symmetry' sides to you 2D problem.
3) Having done this fill in your boundary labels, mesh controls and inflation as normal. When you then hit mesh, it will mesh the 'symmetry" pair identically and extrude 1 element across from one surface to the other.
