How to plot local residuals in pimpleFoam ?

cyln · March 21, 2018, 19:22

I would like to check where the highest local residuals are within my computational domain. How can I make OF calculate the local residuals?

I am using pimpleFoam.

Cheers,
Cyln

Hi Cyln,
Did you solve your problem?

Hello Kerim,

Extend editions of OF have a built-in utility called simpleFoamResidual. You can use that to extract local residual data.

Cheers,
Cyln

Hi,
I am using openfoam 5. How can I used simpleFoamResidual?
Thanks in advance.

I guess you cant. I at least assume that cyln's answer refers to the OpenFOAM ext. family. But there are several other ways to plot the residuals.
You can use the residual function object. See e.g. here (section 6.3.4, for OF 5.x) and here (for OF v1712). Or plot them with gnuplot (Tutorial).
