Dynamic code Openfoam2206 WSL2
 

Hi foamers!

On my windows desktop, i'm using WSL2 (Windows Subsystem for Linux 2) for running ubuntu 22.04.1 LTS (code name : jammy).

After the installation of Openfoam2206, i've tested some tutorials and all the cases with Dynamic code did not work.

By example with the tutorial "multiphase/overInterDyMFoam/twoSimpleRotors".

Below is the output function with dynamic code (i didn't do any change) :

alphaVol
{
libs (utilityFunctionObjects);
type coded;
name alphaVolume;
writeControl timeStep;
writeInterval 10;

codeWrite
#{

const volScalarField& alpha =
mesh().lookupObject<volScalarField>("alpha.water") ;

Info<< "Alpha volume = " << alpha.weightedAverage(mesh().Vsc())
<< endl;

#};
}

When i run the tutorial, i had the following error :

Using dynamicCode for functionObject alphaVol at line 92 in "/mnt/d/twoSimpleRotors/system/controlDict.functions.alphaVol"

For some reasons, the "make" has not been done successfully. Did i miss something during the installation?

Many thanks for your help!

Does dynamic code not work after installing the additional dependencies?

$ sudo apt install bison flex m4 build-essential

Hi Longe!

I've install the addiontal dependencies but nothign works. I've even reinstall Wsl 2, ubuntu and openfoam but i have the same problem.

Hi


It seems that the problem that is happening is a bit complicated. For example, what would happen if you build statically as follows?

$ cd dynamicCode/alphaVol
$ wmake libso

To create dynamicCode/alphaVol, run Allrun once.

Hi LongGe!

The error gone always with your solution

Using dynamicCode for functionObject alphaVol at line 102 in "/mnt/d/twoSimpleRotors/system/controlDict.functions.alphaVol"

deltaT = 0.00117647058824

However i can not find the output file in postProcessing folder???

Hi LongGe!

Everything is ok now. I've found the output in the log file.
I've forgotten the meaning of Info<< command.

Thanks for your help!
