CFD--->Fluent.
 
HI All,

I am wondering if it possible to use a CFX mesh in Fluent? I have meshed the problem in ICEM/HEXA and I wish to use the same mesh in both packages. Any help would be grateful.

regards,

Syaek.

Which CFX package? CFX-5.x, CFX-4.x or CFX-TASCflow 2.x?

Of Course, If you use ICEM/HEXA,You can select what ouput file you want. If you want to output cfx4 file, you should select the cfx4 then set BCF and then select all block to output.it is same mothod to get a fluent file. It's very easy in icemcfd.

It's have not relation with the which package if he use icemcfd/hexa. he can select cfx4,cfx5 tascflow.....and fluent 5, fluent 4........ It's very easy in icemcfd.

Can I ask why you are wanting to do this?

Simple! Mesh comparison between the two packages---fluent and TASCflow.

You said you use icem/HEXA, That is to say there has same mesh between fluent and tascflow, no Mesh comparison between the two packages---fluent and TASCf at all.

Sorry, I missed the ICEM/HEXA part. Don't know how I managed to do that. You are right. CFX-5 and CFX-TASCflow can read HEXA grids. Probably Fluent too.

Note that even though the same mesh (i.e. number of cells/nodes are the same) can be run in both packages, it is not an apples to apples comparison. Fluent is a cell based code (e.g. number of unknowns ~ number of cells) while Tascflow is a point or vertex based code (e.g. number of unk ~ number of vertices of the mesh).

The differences are not as pronounced on hex meshes where the number of cells and vertices are similar. This is not the case on an all tet or tet-prism mesh.
