question when made a new mesh about cylinder2dflowcontroldrl HOT 13 CLOSED

Hi!

Strange, I had not seen this before.

• Are you using the singularity container?

• What happens if you replace the printind by a normal print in generate_msh.py line 11 (and possibly at other locations in the code where printind may be called)? This is where the error message points to.

Another issue I have seen several times is failure to call gmsh from within the program; however at this point it does not look like this is the problem you have.

Yes,I used the singularity container.I replaced the printind by a normal print just now,it didn't work.
Here are my steps: in empty_simulation,i changed jet_angle=5,and then plot=false,last run make_mesh.py.
So I wonder if there are any details i missed.
appreciated your answer

What error messages do you obtain replacing the printind calls by some print calls? Can you show me your terminal output?

still the same mistake.

I am sorry, I do not understand what you did / where the problem is. I know other people managed to change the number and position of jets, and we also did it successfully. Can you turn plot to True and see if something changes?

from cylinder2dflowcontroldrl.

sorry, I mean put back plot=500 .

well ,i will have a try .thank you

As a side note: other people had problems in the past to get the gmsh calls here to work:

https://github.com/jerabaul29/Cylinder2DFlowControlDRL/blob/master/Cylinder2DFlowControlWithRL/generate_msh.py#L35

https://github.com/jerabaul29/Cylinder2DFlowControlDRL/blob/master/Cylinder2DFlowControlWithRL/generate_msh.py#L52

This is because, 'stupidly', gmsh is not installed inside the singularity container.

To solve this there are 2 solutions:

• Export the gmsh provided in the repo to the singularity container: this is what is recommended in the Readme: export PATH="SET_YOUR_PATH/gmsh-git-Linux64/bin:$PATH

• Update the two lines listed above to directly execute the gmsh provided in the repo. For this to work, you will need to first do a chmod to make the gmsh binary executable, and then call it in a ./ fashion in the code.

Well,with the material you offered,I successfully sovle the problem.

from cylinder2dflowcontroldrl.

Great to hear, many thanks for the update!

For the records, what was the problem / which step solved it? :)

from cylinder2dflowcontroldrl.

There are lots of versions 3.+ about gmsh,maybe some of them are not suitable.So I used 3.0.6 that you talked about in readme.md at last,and it works.
I realize that I shuold follow your guideline at the begin,and I can avoid lots of problems.
So kind of you!

from cylinder2dflowcontroldrl.

Ok. Good to know it works when you follow the Readme ;) .
