Hi,

I want to use the actuator disk model for a university project I am doing. I am running on Mac OSX 10.14.6. I am trying to use the turbineSiting tutorial ($FOAM_TUTORIALS/incompressible/simpleFoam/turbineSiting). I can successfully run blockMesh but when I run simpleFoam I get the error:

--> FOAM FATAL ERROR: (openfoam-2012)
cannot find file "/home/ofuser/workingDir/turbineSiting/0/p"

From virtual Foam::autoPtr<Foam::ISstream> Foam::fileOperations::uncollatedFileOperation::rea dStream(Foam::regIOobject&, const Foam::fileName&, const Foam::word&, bool) const
in file global/fileOperations/uncollatedFileOperation/uncollatedFileOperation.C at line 547.

FOAM exiting

I not sure what to do here as the pressure p file is definitly there. It might be worth noting that the folder '0' is actually named '0.orig' for me (unlike some of the other tutorials). If I manually change it back to '0' I then get the error:

No MRF models present

Creating finite volume options from "constant/fvOptions"

Selecting finite volume options type actuationDiskSource

--> FOAM FATAL ERROR: (openfoam-2012)

FOAM exiting

The 'sets' and 'actuationDisk1' directory also doesnt exist, but I'm at a loss as to go from here really.

You need either execute `./Allrun` or need to follow the commands inside the `Allrun`.

Hi, thanks for the reply! I did try running Allrun but when I check the log.simpleFoam script afterwards it contains the same errors as the one I posted above (cannot find file etc). The only difference is that the error is recorded for each parallel processor this time, but the error itself is the same.

[HPE]

interesting. let me try to run the tutorial on my local workstation tomorrow. will let you know.

It may be that the following bit within the Allrun script is not working...

. ${WM_PROJECT_DIR:?}/bin/tools/RunFunctions

If not, then you will not have access to several of the tutorial run functions. Such as "restore0Dir". Is your environment variable set correctly? Try running the following to see...

echo $WM_PROJECT_DIR

Okay thank you. I think a problem was that after I ran the case using blockMesh and simpleFoam and got the error, I used used ./Allclean to clean the generated case files. When I ran ./Allrun I got the errors I posted above. Instead I copied the case again fresh from the tutorial directory and when I run ./Allrun then it converged. I can also successfully view the results in paraview.

I'm still confused however about how to run the case without ./Allrun. I want to use the actuator disk for a project I'm doing but I don't want to have to run the parallel scripts every time I use it. I also wish to cut the mesh down quite a bit as I intent to run a simulation in 2D.

[KimBest]

Also, when I run the RunFunctions line it tells me I don't have permission, and when I run echo $WM_PROJECT_DIR I get: /usr/lib/openfoam/openfoam2012

[HPE]

I kindly suggest you to learn OpenFOAM a bit more by starting to examine the tutorials. The links below may also help.

I'm still confused however about how to run the case without ./Allrun.

`Allrun` is a script containing the commands to run the tutorial. Open it and examine it.

Hi,


In the past few weeks I've been learning much more about the case and have adapted it to my own specific problem, however the fvOptions file still doesn't seem to be working on my machine. It simulates the momentum source but seems to be invariant in it's effect regardless of how I edit the file. For example, if I take the turbineSiting tutorial, completely unaltered, and then switch the diskDir to (-1,0,0) instead of (1,0,0), there is no noticeable change to the results. Similiarly, if I increase C_p and C_t to ridiculously high values (up to say 100) there is also no change. Additionally, if I switch sink to false (from true), simpleFoam returns an IO error with no other explanation.
Do you have any idea what this might be? SHM seems to mesh the turbine area well and topoSet is successfully marking enough cells as momentum sources.

[HPE]

Let me run the case, will let you know.

[HPE]

still pending from my side - I'm sorry. (pef) it is in my mind and list.

[KimBest]

No worries, thanks a lot for getting back to me.


I have now switched to using CFDDFC on amazon's web services to run my simulations. I can confirm that there is something wrong with the mac installation files, as I can now run the simulations perfectly with my chosen geometry.
