Hey,

I calculate a flow around an object, based on the motorBike tutorial.
A steady-state case is set up, that creates a directory at timestep 50 that i want to implement into my transient case. The snappyHexMesh options are the same for both.

Unluckily i am not sure how i can implement the mapFields function into my transient-Allrun.

My steady-state Allrun (solver is SIMPLE, results look allright)
Code:
#!/bin/sh
# Source tutorial run functions
. $WM_PROJECT_DIR/bin/tools/RunFunctions

cp system/fvSolution.OF2.1.0 system/fvSolution
cp system/fvSchemes.OF2.1.0 system/fvSchemes
cp 0.org/nut.OF2.1.0 0.org/nut
cp constant/polyMesh/blockMeshDict.OF2.1.0 constant/polyMesh/blockMeshDict
cp -r 0.org 0 > /dev/null 2>&1

runApplication blockMesh

runApplication snappyHexMesh -overwrite

runApplication decomposePar

runParallel renumberMesh 6 -overwrite

runParallel potentialFoam 6 -initialiseUBCs -noFunctionObjects

runParallel `getApplication` 6

runApplication reconstructPar -time 50
My transient-case Allrun: (solver is PIMPLE)

Code:
#!/bin/sh
# Source tutorial run functions
. $WM_PROJECT_DIR/bin/tools/RunFunctions

cp system/fvSolution.OF2.1.0 system/fvSolution
cp system/fvSchemes.OF2.1.0 system/fvSchemes
cp 0.org/nut.OF2.1.0 0.org/nut
cp constant/polyMesh/blockMeshDict.OF2.1.0 constant/polyMesh/blockMeshDict
cp -r 0.org 0 > /dev/null 2>&1

runApplication blockMesh

runApplication snappyHexMesh -overwrite

mapFields /home/simon/openFoam/nachstellen/startwerte/ -sourceTime 50 -consistent 

runApplication decomposePar

runParallel renumberMesh 6 -overwrite

runParallel `getApplication` 6

runApplication reconstructParMesh -constant -mergeTol 1e-6

runApplication reconstructPar
During the mapping process no error appears in the terminal window. All log files seem okay except for the pimple log!

And this is my PIMPLE log:

Without the mapFields, my case should work. For sure it does without parallel-settings and map-fields.

Big thanks in advance, i am new to this programme (got started 1 month ago) and completely lost. I will give all necessary information, please help me!

I am completely unsure about how to implement parallelization and mapping correctly. I reconstruct time 50 in my steady-state case because mapFields with -sourceParallel doesn't work at all.
I want the transient-case to take the fields from my steady-state case as initial conditions. Am I on the right track?

Best regards,

Simon

Hi Simon,

there's this: "Courant Number mean: 0.135977 max: 5.28681"

It seems a little high. Try to start with a smaller initial timestep. I guess you started with DeltaT = 0.001 ... so try 0.0001 or even lower.

What about MeshQuality, have you checked?

Hey,

Thanks for your advice! I added
"adjustTimeStep yes;
maxCo 1.0;

to my transient case Allrun and now the solver is working.
Good success.

Unluckily the mapping still doesn't work.

Hey simon!

sorry for the lag but I'm quite new to the forum.

It looks like mapFields wants to map the stuff in the "0" time folder (which is not reconstructed). That's why it complains about the empty patch.

You should change your startTime in your target controlDict to 50 and/or maybe create a folder for time "50" as well.

Hope that helps.

B.T.W. it should work without reconstructing to if you give it the options -parallelSource (and -parallelTarget)
