Hello everyone,

i am new to this forum, i am trying to work on inviscid flow with navierstokes instead of Euler,
implementing SA solver, when i am trying to run, i got this error, please help me out.

Thanks & regards

Are you modifying the code? It's not clear how you are trying to simulate inviscid flow - navier stokes is a viscous solver, and SA is a turbulence model, which means you are not simulating inviscid flow. If you are trying to use a turbulence model and viscous flow, use RANS instead of navier stokes - navier stokes does not use the turbulence models.

hello, thank you for your reply, yes i am trying to change the code using navierstokes on in-viscid flow, i want to check the output based on the bump problem..

First of all, I want to give you the link to the developer docs, which has lots of information relevant to modifying the code:
https://github.com/su2code/SU2/wiki/Developer-Docs

It is not clear what you are trying to do, as the navier stokes equations generally do not apply to inviscid flow, and this error will depend highly on exactly how you are modifying the code. However, my first guess would be that the problem lies in the option_structure.* or config_structure.*.

I would recommend using and IDE such as Xcode or Eclipse to find all the instances of the options related to the closest existing functionality. For example, starting from solver option in config_structure.cpp you can see that it depends on the solver_map for the list of options. That map is in option_structure.cpp, where you can see that to add another option you need to modify both solver_map and ENUM_SOLVER. Using an IDE to find all the instances of a particular solver name will help you find all the places in the code where modifications are needed to introduce a new solver.

For finding specific problems (due to the nature of coding, you will have more of these as you continue to modify the code, and the general error type will only be useful if you know what has changed in the code), I recommend introducing print statements or looking into debugging programs to help you figure out exactly where the problem is occurring. IDEs sometimes provide hints as well.

thanks a lot, i will do that.
