Hi

I am running a transient simulation using pimpleDyMFoam with nOuterCorrectors as more than 5. Hence I would be getting more than 5 Pimple iterations per timestep. Lets take 5 as an example.

Following is for a single timestep:
Code:
Courant Number mean: 0.0768848 max: 0.484731
deltaT = 0.00266306
Time = 0.052065

solidBodyMotionFunctions::rotatingMotion::transformation(): Time = 0.052065 transformation: ((0 0 0) (0.986653 (0 0 0.162839)))
AMI: Creating addressing and weights between 96 source faces and 96 target faces
AMI: Patch source sum(weights) min/max/average = 1, 1, 1
AMI: Patch target sum(weights) min/max/average = 1, 1, 1

ExecutionTime = 1.58 s  ClockTime = 2 s
I would like to plot final residuals for each pimpleIteration. I am flexible using foamLog or pyFoam also. But I do not know how to use them.

I have seen such plots in openfoamwiki in the following link
https://openfoamwiki.net/index.php/O...hm_in_OpenFOAM

Any suggestions or help please.

Hi

if I am not wrong, you can use foamLog, and each corrector will be expressed as

Ux_X
UxFinalRes_X ...

where X is the number of the outer corrector (it starts from 0)
