Hi Fabian, 

I wanted to know could you come up with any solution of how to use the compressible flow solver in Nektar?

I could come up with a better mesh for my case and I am able run the compressible flow solver with P-4,

but residuals are still good at all. Below is the mach contour obtained at time 1sec simulated at a time step of 0.0001.

Furthermore, if I try to solve it using CFL tool, it terminates for all CFL values more than 0.1(which is not good). 

What about your status? 

Can anyone help me out of this situation? 

Regards, 

Dev
