Add the options `-ns` or `-v 0` to your command line?

Thank you, I’ll be more specific.  
I have create an edp file for thermal problems of concrete section.  
Because of Freefem native poor quality plot, I have implemented edp file  
in a python script to create high quality plot.

 ![plot01](https://canada1.discourse-cdn.com/flex030/uploads/freefem/original/1X/28f18309564ccbcf2fbc44a45a7c4319c5b4c0ca.png)  
Now, I need to know if there is a way to not create file log at the end,  
maybe with a command directly in the freefem file (edp).  
Thank you!!!

I don’t understand your question. If you want to create high-quality figures and animations, use ParaView, not Python, with the `savevtk` plugin. Here is an [example](https://github.com/FreeFem/FreeFem-sources/blob/develop/examples/plugin/ttestio.edp).

Hi!!  
With these few lines:

_import subprocess_  
_process = subprocess.Popen(‘FreeFem++ yourfile.edp -ns’, stdout=subprocess.PIPE, shell=True)_  
_output, error = process.communicate()_

you can call your freefem file (edp) and running it from the python script.  
In my project, I use the python script for input values/plot results,  
and edp freefem file as FEM solver.

Hope this can help you.  
Best regards!!!

Thank you very much for your swift reply!

Do you write the result to temporal files, and use python to read it?

Thank you!

Yes!

1. I use python script to write inputs (txt file);
2. freefem edp reads inputs and solve the problem, creating output file  
(mesh points, elements, data values in a txt file);
3. python script reads this output file to create plots;
