[clarified and WIP] butterfly doesn't work with OpeFOAM v1606

I got the following error testing the outdoor demo file for butterfly:

I followed the advice on https://github.com/mostaphaRoudsari/Butterfly/wiki/Getting-Started-... and changed the container name to "of_plus_1606" in the runmanager.py script file based on the output of "docker ps" in docker terminal:

However, the error is still here, and I can't proceed to the rest components in the workflow...

The demo workflow can generate the "outdoor_airflow" project folder in the C:\Users\USERNAME\butterfly folder

So, I start OpenFOAM using the start_OF.bat file, and I can manually type and run the following OpenFOAM command: blockMesh, snappyHexMesh, checkMesh, manually change some of the parameters in controlDict and fvSolution.

However, I got the following error when running simpleFoam, and the calculation is aborted.

May I ask:

why the blockMesh component is not running even if I changed the container number in the rummanager.py as suggested?

Why the manual running of OpenFoam failed?

Thanks!

Just fixed it for both vector and numerical values. Update butterfly and try again. If the issue persists please open a new discussion.

Butterfly last updated should be: 2016-08-23 10:45:00

Hi Olivier, glade to know that you're testing Butterfly, too!

Just to clarify that I'm not in the developer team of Butterfly, and I myself is a user like you who is very interested in this new "bug" for CFD. So, apologize if I'm not able to help you with your questions here.

Dear Theodoros, thank you for the updating!

I posted a new problem I encountered here when step 1.2 in the outdoor airflow demo file is not bypassed. Hope the team can kindly advise.

Thank you all!

Hi Olivier,

Have you made sure you updated BF before running the case? There was an error in creating initial conditions and cases would diverge.

This is what seems has happened to your case. If you see, the results indicated in the error for pressure are, well I don't think I know the name for those numbers. But values of XE+118 mean the simulation was diverging. I would recommend you to update BF, if you haven't already, re-run the case and test after.

Also, you can post your mesh settings here. Most other times is mesh quality causing this.

Kind regards,

Theodore.

I take it back!

Sorry I spoke too soon, from the file you provided the results seem ok. I believe Mostapha will have more on this.

Regards,

Theodore.

Hi Theo,

I have indeed read the earlier thread on the initial conditions.
I did go through updating it, closed, reopened... I remain not confident with the different permissions and rooting of folders, as Im running Windows 10 on Parallels on a Mac. However I have been using a lot of softwares and have always found solutions.

Please find attached the GH definition in which you'll see that I have not made significant changes, apart form increasing the reflevels of the wall boundary, thinking they would have to be comprised in the globalRefLevel of the wind tunnel. Also the wind speed.

Thank you for reaching.

Kind regards,

Olivier
