How to extract Differential Equations Matrix Coeff
I'm pretty new in OpenFoam world, but not in CFD. I've spent 3-4 months working with OP so I have the generals although my field are mathematics, not aerodynamics.
I'm working on differential equations systems acceleration using hybrid methods (CPU-GPU) for my thesis.
My question is:
How can I get an output of OP with the coefficients matrix (the matrix which OpenFoam solves later)?
PD: - I will publish the results and the source under GNU license.
- Sorry about my english
Thanks for your help.
I'm still trying to find the way. This link helped me, so perhaps it could be useful for someone. :D
Samuel, if you want to extract these values at debugging time and many other debug hacks you have gdbOF
Coeff. Matrix. It's correct?
I've been working with other stuff for some time so I've come back with OpenFOAM.
I've write out the matrix coefficients in a file for the cavity (2D) tutorial solved with icoFoam.
Note that coeff.  is on the left bottom
My question is, it is correct the addressing? Are there additional terms out of diagonals? (Wiki' figure is different from mine but I'm not sure if that would be extendible for 2D cases or only for 3D ones... :confused:)
I'm reading some post of addressing... Thank you in advance.
