Hi,

Is there a way to avoid automatic save for all computed variables in OpenFOAM? My OpenFOAM simulations produce many variable fields including u, p, alpha.water, k, nuSgs, etc.

Is there an option in the dictionary files so that only selected variables are saved? Doing a modification of the source code may be more challenging so if you know a possible option, i would be happy if you inform me.

Thanks

Actually, compiling your own solver is very easy. To answer your question, look at the source here: https://github.com/OpenFOAM/OpenFOAM...eFluidFields.H


You can see this block:
Code:
                IOobject::NO_READ,
                IOobject::AUTO_WRITE
Simply make NO_WRITE for the variables you don't want to write out.
