Hi

I am new to CFX. I was wondering if we can develop a structured mesh in CFX. If yes, Can you kindly tell me where to locate the required information.

Thanks a lot for your help.

Hi Ram,

You should first specify as to what preprocessor u are using? Is it build/ Cadto mesh/ ICEM hexa?

I am using Build as the processor.

Thanks

Ram

Yes you can create the structured mesh in Build. I suppose you are using Build-5.. If so you will have to create the block structure first and then change the meshing mode to Patran volume meshing. (Tools--Mesh Mode). NOte than if you are extruding surfaces to create solids, you will have to create solids, you will have to choose the iso-meshable option to get blue colored solids which can be meshed with structured mesh. You cannot mesh B-rep solids with tructured mesh.. Then create the mesh seeds and solid mesh. (while creating solid mesh make sure you have selected the Hex mesh elements only). Equivalance nodes to delete duplicate elements and write out the mesh. Mesh will be written in Neutral (*.out) format. Note that all 2D regions have to be defined in Build itself (after changing the mesh mode). NO region can be accessed in Pre for a neutral mesh format. You neednot create surface mesh

Let me know if u need any further assitance or if u r using Build4

Let me know if u r using Build4

Thanks a lot for your inputs. I shall explore the options. I am using Build5.

Are there any examples or links wherein I can learn more on structured mesh.

Ram

Nope..

If you want to learn block structuring, lot of Build examples are avaliable in Build 4.. If you have CFX-4.4 you can see the Build example section.... Contact you local CFx representative who will be able to provide you an example for this case.//

HI Ram, check some of the previous posts, I've provided details for people in the past Bob

I am trying to solve a combustion problem in CFX where am using a geometry created in Gambit. There was no problem importing the geometry in parasolid form but while meshing in CFX build I find only two nodes on a small inlet whereas I want some more nodes on that surface. I have tried to obtain that by controlling the mesh control values but did not come up with the expected result. Can you help me solve that problem
