Dear developers and users:

I am trying to run 2D sphere and cylinder at hypersonic regime (Mach 10 to start). When I implemented limiter in second order scheme, the only limiter that works is "VENKATAKRISHNAN". With "MINMOD" I got "Segmentation fault" as error message when the solver tries to begin.

Has anyone used limiter MINMOD in the simulations? I want to use MINMOD to compare results with another code. Thank you very much!!!

Hi,

The latest version of the code in the GitHub repository includes the bath's limiters.

Cheers,
Francisco

Hi Francisco,

Thank you very much for your reply. After using Berth Jespersen limiter, I still got a quite big difference in the Mach number at the symmetry axis (I am using this variable for comparison) between the two code. But I don't think that difference is due to the limiter (maybe it does).

I am still doing some tests, maybe later I will post some final results to share with the community. Thanks for developing and sharing SU2.

Cheers,

Facundo

Thanks Facundo,

My recommendation is to use

% Output residual values in the solution files
WRT_RESIDUALS= YES
%
% Output limiters values in the solution files
WRT_LIMITERS= YES

so you will be able to visualize residuals and limiters and detect if something goes wrong.

Cheers,
Francisco
