NEMO - SU2 NONEQ with 3D-grid (Euler or Navier Stokes) doesn't start
 

Hello my friends I´m new here and my research area are hypersonic waverider geometries. I´m intersting to do some simulations with NEMO-Navier_Stokes und der Air-5 library, but when I start my simulation it ends at the point "NO Jacobian structure" and the calculation doesn't start ... (please refer picture)
Is the NEMO-Solver actually not yet suitable for 3D grids (in my appendix is the config-File)?
Thank you for your answers.

Hi Maximilian,

Thanks for using NEMO! and thanks for your question. NEMO works for 3D simulations.
The no jacobian structure is all good, this simply means you are running an explicit simulation. I am in the process of verifying the implicit capabilities.

Unfortunately, one of the biggest issues with NEMO is speed. Running large grids will take a while to get through the preprocessing stage and is best done in parallel. The link with Mutation++ runs much quicker (though is still slower than a typical simulation).

Id be happy to help out with other problems you may run into and try to help.

Best,
Wally
