Geometry translation
I want to rotate and translate a geometry to a new location. How do I do that?
:confused: |
If you are using STAR CD use the vgen command. For translation you can use this directly. The syntax of this command (explained through an example is):
cset all vset news cset vgen,2,0,vset,,,dx,dy,dz (replace dx, dy and dz accordingly) The above example is for translating. You'd have the Cartesian co-ordinate system on in such a case. If you want to rotate the geometry activate the cylindrical co-ordinate system and then use the vgen command to rotate. |
Sorry forgot to mention that if you are using STAR CCM+, it is straight forward. Right click on the region and you'd see the transform option. This has rotate, scale, translate options.

It is working well. Thank you. I am using starcd 3.26.
If I want to add a new mesh using current surface model on top of the top layer of a previous mesh, what can I do? |
You can create a surface mesh (shells) at the top and then extrude it (see help for VCEXTRUDE command)
|
what commands are normally used to create a surface mesh (shell) from vertices?
thank you. |
If you already have a 3D mesh, you can use CFIN command with SHELL option (from GUI: Tools->Cell Tool->Add Shells->Surface (New edge Vertex Set)...)
