Hi everyone,

I’m a first time SU2 user for my undergrad research project. I’ve downloaded the current release for Windows 10 and followed the Windows Installation doc. I have successfully run the compressible Inviscid Bump in a Channel and Laminar Flat Plate tutorials, so I know that my setup is correct.

My issue arises when trying to run the incompressible Turbulent NACA 0012 tutorial (https://su2code.github.io/tutorials/...lent_NACA0012/), the one most relevant to my work. When attempting to run SU2_CFD in serial with the config file (turb_naca0012.cfg) as found on the repository, I get the following error:


Error in "void CConfig::SetConfig_Parsing(char*)":

I tried to comment out these variables in the config file to see if anything would change. When I do this, it looks like SU2 sets up the solver and does everything up to solving the problem:

I noticed that the current release for macOS/Linux is v6.1.0 while for Windows it’s v6.0.0. Is the solution simply that I need to be using v6.1.0? If not, any help would be appreciated.

Thank you in advance for the feedback,

Nathan

Hi Nathan,

I just tried to run the case in v6.1.0 and it works.

Cheers,
Pedro

Hello,

I believe options starting with "INC_" are not compatible with 6.0.0 version of SU2. If I recall correctly they were added with the incompressible solver at version 6.1.0. You'll need a template suitable for 6.0.0 from the github page.
