[Pointwise] 3d t-rex meshing
Dear all.
I'm encountering a problem creating a 3d trex grid in pointwise. i have no problems making it in the 2d domains, but when i build the block, it is filled by isotropic tet elements, and it does not maintain the uniformity of the mesh i carefully created at the boundary. any tip or insight will be welcome. EDIT: i'm using V16.04 r2 if it can be important. |
sail,
The reason is simple - 3D T-Rex is not implement in Pointwise yet. To use 3D T-Rex you need to use Gridgen. To do so, export your mesh as is to the Gridgen format (File > Export to Gridgen ...). Start Gridgen, import the mesh, run the unstructured block solver and set the same T-Rex parameters you did for 2D in Pointwise. You may want to refer to Gridgen tutorial #13 for an overview. 3D T-Rex is slotted for the next major release of Pointwise. -Chris |

i tried to do as you reccomanded, but gridgen (v 15.11) says that the pointwise file format #22 cannnot be imported, because gridgen only supports format #17. any chance you know which version are compatible? |
15.17 is the latest release of Gridgen so you're using 6 versions older. There have been many changes since 15.11, some of which required changes to the file format. Update Gridgen to the latest version and it will work.
