MATLAB postProcessing woes

tLashbrooke · January 7, 2018, 06:48

Hello all,

I'm doing a project with OpenFOAM and wanting to use MATLAB for post processing but have hit a slight barrier when it comes to extracting data from the forceCoeffs/forces/bins DAT files.

Can somebody help me understand how to get readable data from this file programmatically? MATLAB just doesn't want to know!

force.dat

force_bins.dat

Hi,

Matlab does not like '(' , ')' or text strings as maybe you already know. So if you want to avoid to delete it manually with the find and replace method in your favourite text editor, then I suggest you to write a little script in bash which will do the job for you.

Yeah, changing the output to raw sorted out the majority of the data, the rest I used pyFoam to convert into .txt files for Matlab. The Allrun is coming along nicely now!
