error in running example.ABL.flatTerrain.neutral

[yulins]

Hello guys

I am trying to run the "example.ABL.flatTerrain.neutral" case as a starting point to learn SOWFA. The environment is Ubuntu 16.04 + OpenFOAM 2.4.x. I managed to produce the mesh with ./runscript.preprocess, but when excuting ./runscript.solve.1, it fails and the error messages come out in "log.1.ABLSolver" and "log.1.setFieldsABL"

As indicated in the log file, I didn't find anything called processor0. Am I missing some step?
I tried to search for the answer but no success. Any help is appreciated. Thanks.

Kind regards
Yulin

When you ran runscript.preprocess, did it run decomposePar? This should have partitioned your mesh into separate processor directories and mapped the initial solution to them.

Many thanks @ewquon for your swift response, and you are absolutely right. The decomposePar didn't run correctly, as I changed the default 216 cores in the setup file into 4 (i.e. my personal computer), so the decomOrder didn't agree with that. So, I made it back to 216 cores and the decomposePar can now produce correct partitions (there are processor0-processor216 in the folder). Now the only modification that I made in the setup file are 'Number of cells' intending for a more coarse mesh.

However, I still can't make the solver work, and it seems from the command line that the solver doesn't start at all. Is it becasue I set the wrong core value?

Thanks again.

[ewquon]

Looks like your runscript.solve.1 has something wrong in there. You probably still have cores=600 set; this should be the same as nCores in your setUp file.

The cp error is suspicious. This should be run from inside your case directory, i.e., the directory that contains your setUp file as well as the system, constant, and processor* subdirectories.

[yulins]

Thanks again @ewquon for following this. Yes you are right, the cp error is a trouble, as the cd $PBS_O_WORKDIR didn't find the correct path in the 'runscript.slove.1' file. Another thing I figure out is that we should never use 'sudo' in compling SOWFA and its cases, as this will lead to many command permission troubles. Now it seems the ABLsolver is working, and I looking forward to see the results with paraView. Many thanks for your help.

[SH-Liao]

hello @yulins ,I'm facing the familiar problem.I just can't fine out where exactlly $PBS_O_WORKDIR leads .would you mind to tell me where it leads? when running 'runscript.slove.1',it apears to "cp system/contrilDirt.1 :no such file or directry".please help

[yulins]

Hi @ShenghaiLiao Just simply comment this out with #cd $PBS_O_WORKDIR, and open terminal in the example case, it will find the path.

[SH-Liao]

hlleo @yulins ,thanks for your answer.I tried cd $PBS_O_WORKDIR ,but it simply returned to my home directry,when #echo $PBS_O_WORKDIR it comes out with nothing
by the way ,my foam is at $HOME/OpenFOAM/OpenFOAM-2.4.0,
and SOWFA is at $HOME/OpenFOAM/$USR-2.4.0

[yulins]

Hi, I mean just comment it or delete it. The runscript.solve.1 should be excuted in the examplecase folder, such as' example.ABL.flatTerrain.neutral', than it will find 'system/controlDict.1'

[ewquon]

$PBS_O_WORKDIR is an environment variable from the Moab/Torque high-performance computing (HPC) environment. If you're directly running this script or using another HPC environment, then you should comment/delete that line as the previous commenter suggested.

Hi ,everyone. I was trying to run example.ABL.flatTerrain.neutral. I modified runscript.preprocess:


and in the runscript.solve.1, I changed "source" and "cores":

In the setUp, I just modified ncores and decompOrde

Then I fellowed the step,./runscript.preprocess next ./runscript.solve.1
But it failed:

Where are those libraries in your computer? OpenFoam needs to know the locations of those libraries..
If, assuming that those libraries are located inside a folder like this ${HOME}/SOWFA/applications/lib/${WM_OPTIONS}, then you must add this path to LD_LIBRARY_PATH env variable, before you launch your OpenFoam commands, like this:

export LD_LIBRARY_PATH=${SOWFA_DIR}/lib/${WM_OPTIONS}/:${LD_LIBRARY_PATH}

Besides that, do you have any suggesstion about my error.

[pablo-benito]

But, you still have the error about not finding the libraries? If that's true, please check that the path that you plug into the LD_LIBRARY_PATH is the correct one.. Check that those libraries are actually there..

Also, you can safely remove the command 'of240' of those scripts. They are intended to load the correct openfoam inside NREL facilities. It's just to load the OpenFoam environment, exactly as the command source ${HOME}/OpenFOAM/OpenFoam-2.4.0/etc/bashrc

Hi Cookiewyf,  To get rid of the Warning "could not load "libSOWFAfiniteVolume.so", you could go to the /OpenFOAM/SOWFA-2.4.0/src/finiteVolume/Make/options,   then add "-lfiniteVolume" in the end of the "LIB_LIBS =" It works out for me.  Please try~~  Yi  Cookiewyf ***@***.***> 于 2021年11月5日星期五 GMT+8 上午12:05:39写道： libSOWFAfiniteVolume.so: cannot open shared object file: No such file or directory libSOWFAincompressibleLESModels.so: cannot open shared object file: No such file or directory Where are those libraries in your computer?
