Postprocessing with matlab

giack · July 25, 2013, 10:58

Hi to all,
I want to do my postprocessing with matlab but I have some simple questions.
During mesh generation OpenFOAM create some files with a list of points and faces. The points created are the vertexes of each cell. The output file of the simulation are U and p that are stored in the centre of gravity.
Obviously for the postprocessing with paraview or Tecplot there is a matrix that link the value of U and p with the centre of gravity of each cell. Where is it?
In matlab I'm able to find the cells centre of gravity but I don't know the order
whereby all field variables are stored.
Any suggestions?
Thanks to all

Hi giak,

what you need is writeCellCentres utility. It writes cell centres as a field.
