Convert / transfer Fluent data to OpenFOAM 3.x

PeterPete · September 9, 2016, 06:50

Hi I'm trying to convert my steady state solutions from fluent to openfoam. Mesh and boundary conditions work fine. I tried using writeCellCentres combined with exporting my solution data in fluent to the Cellcenters, but ccx/ccy files don't follow the mesh exactly (digitizing). This makes mapping the data via Python kinda difficult. Maybe I'm googling wrong but i could not find any good solutions. Help would be greatly appreciated.

Okay i found a possible way to do this in python. The idea is to use the ccx and ccy files, take one point, and calculate the difference ((cxx-x)**2+(cyy-y)**2 )**.5 to all points in the fluent file. the minimum is then mapped to the point in the openfoam data file. not finished yet but i guess this will work.

You can use fluent3DMeshToFoam to import mesh and fluentDataToFoam to import data to OF

Hi hiuluom,
thank you for your answer. I already used to import the mesh via fluentMeshToFoam\fluent3DMeshToFoam. I read about fluentDataToFoam but I am not sure how to use it in Version 3.0.x of OpenFOAM.
If you know a link pointing me towards the use of fluentDataToFoam, it would be greatly appreciated.
