Hello everyone,

I'm trying to run a case on saturne 2,1,4.

This case use a particular physics « gas combustion ».
I use a xml file created with SaturneGUI

so I add in the:
DATA directory, the dp_C3P file

SRC direcory, the usppmo.f90 file with ippmod(icoebu) = 2
the usebu1.f90 usebui.f90 and usebuc.f90 files


Here is the error I obtain:

It's seems that the dp_C3P file is not found...

Is there something special to do in the runcase?

I tried to add in the DATA directory the cs_user_scripts.py
and modify the line domain.thermochemistry_data = 'dp_C3P'


but the error is the same.

Can someone help me?

Thank you very much

Sylvain

Hello,

This might be either us user error or a bug related to to the name of the dp_C3P file (as different combustion variants use similar names).

In your temporary execution directory, do you have a file with a name similar to dp_C3P ?
Otherwise, could you post your study here ?

Best regards,

Yvan

Hello Yvan,

The dp_CP file is not in the temporary execution repertory.
I add the case and the mesh in this post.

I tried with colecd to write ficfpp and the result is not dp_C3P but dp_thcp

Thank you for your help

Sylvain

Hello,

In the cs_user_scripts.py, you commented the "if domain.param == None:" line before setting domain.thermochemistry_data, but you did not change the indentation for the chemistry data. As Python bases its scoping on indentation, this means that the domain.thermochemistry_data is set base on the previous test, relative to domain.meteo_data.

If you simply replace: by: then things improve, and the file is read.

Running your case, I get another error, which is:

The kernel variables number 8 and the calculated one by the GUI 6 are not the same.

Meaning there is a conflict between the numberof variables determined by the GUI and that determined by the user subroutines and specific physics.

As gas combustion is not handled by the GUI yet, I guess the GUI does not read the dp_C3P file, the number of variables computed is false.
Solutions would be either:
- add variables in the GUI matching the ones that should be added by gas combustion so that checks may proceed (this might work, but I am not sure it is safe)
- assume that gas combustion is not handled by the GUI yet, and do the data setup using only user subroutines.

I checked the gas combustion is not handled by the soon-to-be released version 2.2, and I do not know whether it will be in 2.3 (around June/July) or in 3.0 (I can check with collegues), so for the short term, using user subroutines might be a safe bet.

Best regards,

Yvan

Thank you very much Yvan,

I will try without Gui.
