Hello

I wanted to run Foam on a model generated by Fluent(Gambit - Fluent *.msh file)
I opened up a new Folder with a case name and copied concerned source files..something like turbFoam.c and related files.

I ran 'fluentMeshtoFoam root case' but it could not read controlDict File. So I created constant and system folders in the case folder manually.
I then tried running Fluentmesh conversion and it created polymesh and other files.

I would like to know, how to generate the initial mesh fields p,Rho, U etc in the '0/' folder with dimensions and specified fields..

Also, "meshDescription" file in the polyMesh was not created by the 'fluentMeshtoFoam' Utility. How can I scale the grid to mm ? should I run blockMesh after fluent to Foam Mesh conversion ?

You can create a new case or copy an existing one in FoamX. This will take care of setting it up for the desired application (icoFoam, turbFoam, etc.).

The only thing different for your case would be the mesh generation phase where you don't run blockMesh but a mesh converter instead.

To scale a mesh use scalePoints which takes root,case and three scaling factors. Just use

scalePoints -

to see the arguments.

how did you know th escalePoints,

where can i get the similar information

Take a look in the utilities directory.

I'm on version 1.2 and it seems that the utility scalePoints is gone, can't find it in FoamX or as a function in console. So how can I scale my imported mesh?
Thanks.

Try something like:

transformPoints <root> <case> -scale "(1e-3 1e-3 1e-3)"


Enjoy,

Hello!
I'd like to create a simple but HUGE(~500^3) block structured mesh from voxel tomography data.
(file of binary values 0,1, cubic blocks)

I tried to create a blockmesh dict with a script but I run out of memory when using blockmesh.
Also the mesh finally has to be decomposed for multiple CPU.

Does anybody have a idea how i can handle this problem.

thanks
