multispecies plasma test case
I've just installed the newest 2.0.8 from github.
I'm trying to run the multispecies reactargon case, and am getting a lot of errors. I'm using the config file from the newest release. see below:  SU2_CFD plasma_argon_3D.cfg WARNING: unrecognized option in the config. file: MIXTURE_MOLAR_MASS.

Hi Tom,
The reactinggas solver is currently undergoing a complete overhaul and, unfortunately, the test case in the repository and in the user guide is outofdate. I apologize for the inconvenience, I've temporarily removed it from both locations until I can appropriately document the changes and set up a proper testcase for the community. Thanks for bringing it to my attention. The new implementation will be finished in a month or two and I encourage you to stay tuned for updates. Thanks. Regards, Sean 
I actually got the first part of it to run by checking and rechecking the input items and config_structure.cpp and taking out the wrong and discontinued items.
I started it euler, and it runs and gives me a solution that looks proper. However, no matter what I try, I get nan's when restarting. Whether I run 25 iterations and restart or whether I run 15,000 and restart. 
Hi Tom,
I'm glad to hear that you've seen some life in the reactinggas solver. There are likely settings in the configuration file that are referencing defunct and obsolete subroutines within the old reacting gas solver that are contributing to your difficulties. The old code will be removed for the next interim release. This may also be contributing to your restartfile issues. Francisco and I sent you a mesh and configuration file the other day, I would encourage you to try running that case as a starting point. Be sure you are referencing the TNE2_EULER solver (NOT the PLASMA_EULER solver), and set the GAS_MODEL=N2. Again, I want to stress that the reactinggas solver is not supported at this time. Many of the settings are not welldocumented. If you continue to have difficulty, please send me an email and I will do my best to assist. Thanks, Sean 
Yes, I planned on continuing with that tne case you sent earlier... thanks for that.
I'll hold off on the plasma case for now. 
Removing this reply to post elsewhere.

Hi,
I am currently using the 4.0.2 version of SU2 and not being able to find the configuration file for plasma solver. Can you help me with it. Thank you, Suraj
