Hi,

I am having trouble launching patchTool. I am a new user of OpenFOAM, and am not particularly competant with linux so it is likley that the problem is quite simple.

On trying to launch patchTool I get the following infomration in the shell window:

james-1.4/run> patchTool . device-steady/
runPatchToolServer : pid:8263
Using running runPatchToolServer (pid 8263) ...

Any ideas on what I have done wrong?

Thanks

Probably this is because you have an extra "/" in the case name. You should type:
patchTool ./ device-steady

Hi Dragos,

Same problem. I have tried quite a few different variations on the cmd line, all give the same error which I think comes down to this line:

Exception in thread "main" java.lang.NoClassDefFoundError: javax/media/j3d/Node

Do you know what that means?

[dmoroian]

Hm, no idea! But is seems there is something wrong with the java installation. Is FoamX running correctly?

Yeah it sounds possible, however both FoamX and paraFoam work perfectly.

Pehaps there is another way to achieve what I am trying to do. I have a single patch (a pressure inlet) which is in reality 3 separte inlets, each oriented in a different direction and not touching.

I would like to change this to a velocity inlet, however since the definition of the inlet velocity is cartesian and not magnitude normal to the boundary, I need to split this single patch into three separate patches.

Without patchTool is there another way to do this?

Hi,
Just a guess but maybe it's because the Java3D library (https://java3d.dev.java.net/binary-builds.html) is missing from your Java installation. Try installing the library following the installation instructions in the README on the page.

I think I have now fixed my java install. The pathchtool GUI launches, now I just have to work out how to use it.

Thanks for your help.
