Hi all,

today I added a new tutorial that is using sHM to create a AMI for a spiral conveyor (just very simple). Of course there are other ways to make the AMI interface (setSet and createPatch -> baffles) but here it is:

hello holzmann
when I run spiral conveyor I am getting this error

- Update AMI patch infos / also changeDict could be used
./run: line 48: createPatch: command not found


-------------------------------------------------------------------------------
End Meshing





Start moving the mesh (could take a while)
-------------------------------------------------------------------------------

- Run application moveDynamicMesh
./run: line 67: moveDynamicMesh: command not found


-------------------------------------------------------------------------------
End of moving

Dear Alex,

as you can see from the messages there is a problem in your FOAM installation. createPatch is a foam application. If you load your foam variables and type createPatch you should get some output. You can check it like that:

source $HOME/.bashrc
which icoFoam
which createPatch

If there is no output for the last command, then your FOAM installation is not correct.

hi tobi
I am trying to run propeller simulation using PimpleDyM foam. my solution is not converging. please tell me if something is wrong. I will post my checkMesh, controlDict, Fv soltuion,files.

Can someone upload this tutorial? Link is unavailable.

Thanks for the note. I repaired the link (need a while after it will be available). Finally, you could solve the problem yourself if you took one minute to check out my site. Well here is the link: https://Holzmann-cfd.de

Maybe the new one is also of interest: http://www.cfd-online.com/Forums/ope...-tutorial.html

holzmann,

On clicking the new tutorial link, it is directing me to your login page. There is no option for registration.

May I know how to register for your website?

Hello,

I am sorry that you cannot access to my website right now because I am working on it. However, questions like yours make me sad because it demonstrates that people don't read anything :/. If you just read the two sentence that I provide you would know what is going on:

Dear fellows, cfd enthusiasts and FOAM'er. I am working on my page. --> Numerical Schemes are going to be extended with a polygon mesh and all data are recalculated and automatized (scripts will be included that everybody can use it for the research). Kind regards, Tobias Holzmann

I am sorry that no one has actually access to it. I am working on it. Today in the evening my site should be available again.

Kind regards,
Tobias Holzmann
