Hi,

I am wondering if anyone has had any success with installing ESI's OpenFOAM for Windows. I got it installed and when I started the OpenFOAM_start program, I got a registry editor error.
Set-ExecutionPolicy : Access to the registry key 'HKEY_LOCAL_MACHINE\SOFTWARE\M icrosoft\PowerShell\1\ShellIds\Microsoft.PowerShel l' is denied.

As it turns out, the advice on this
http://answers.microsoft.com/en-us/w...9b31bf5?auth=1

page is good. I just edited the registry and the error went away.

Now, I get a green "Welcome to the OpenFOAM Windows Version (v3.0+)
A bash shell will appear with OpenFOAM environment set.
********************************


I never get a bash shell. Does anyone know how to fix this?

Thanks,
Chris

All, there is a PDF in C:\Program Files (x86)\ESI\OpenFOAM\v3.0+\Documents called OF_Windows_Guide.pdf. It provides essential information for installation. For example, I needed to enable hardware virtualization in my BIOS. That, by the way, is found under Security->System for this AMD processor I have.

So far so good. I have a icoFoam -help working. I don't know where the examples are yet, but I have also not finished reading that PDF. At least OpenFOAM is installed.

Thanks for all who viewed.

Hi,

Sure, You need to use the program regedit. It's part of windows. In that link, it should provide a directory path to go to. Then they have you loosen the permissions.

Does this help? I'm not quite sure where you are stuck,

Best,
Chris

yes, i managed to get rid of the big red error msg and every thing seem running fine now! thanks Fisichel!

did you go any further from here? i tried to run the tutorial and i manage to get the Icofoam work however i'm having hard time to locate all the boundary condition file, and mesh files etc. the "OF_Windows_Guide.pdf" mentioned that the ‘cd /home/ofuser/workingDir’ is correspond to C:\Users\UserName. but i couldn't find any openfoam related file over there other than bootdocker files and some associated VM files.

without knowing where those case files located i can't change the parameters in the file as well as reading the result with paraview.

Hi Max,

If you have the command window, it has the black screen. Then, you should be able to press the enter key and get a prompt:

$

The first thing I do is
$cd workingDir
$ls

that listing should correspond to
c:\users\<your login>

You can copy most of the examples that are located at $FOAM_TUTORIALS to this workingDir, then you can use Notepad++ to edit the case directories.

To execute the Allrun script that is every example, you need to be in the shell. A typical job starts like this for me:

$./Allrun <enter>

Then, I use Notepad++ to look at all the log files that are generated.

confused about ./Allrun? Don't try to use icoFoam directly unless you are working with the cavity example that is part of the OpenFOAM users guide.

Best,
Chris

Hi Max

Try:
$ cp -r $FOAM_TUTORIALS/ ~/workingDir/

If that works, try
$ cd workingDir/tutorials
$ cd incompressible
$ cd icoFOAM
$ cd elbow
$./Allrun

You'll see the cavity examples in the icoFOAM directory. I'm suggesting you go to the elblow example, because all you need to type is ./Allrun.

As for Paraview, I do install Paraview for windows, but it does not work all the time. Of the four machines I have tried it on, it only works on two of them. I hope it works for you, since this is your first time.

Best,
Chris

Thanks Chris,

I follow the step that you gave me it throw me the same error too (see the attached picture)

I look it around and found this commend allow me to "export" the file to .foam file

elbow]$ touch filename.foam.

however, i could only manage to display the mesh (model shape) but couldn't display the P and U value.

That's what I meant when I wrote most of the tutorial can be run in the workingDir.

The case study that is affected is for heat transfer.

Your elbow case should be unaffected.

Did you run ./Allrun in the elbow directory and wait?
