I am attachng the xml that i am running with the solver and the screenshot of what appears once I run the command "CompressibleFlowSolver oct.xml". Besides that, I have another question. What is the maximum Mach number that the solver can handle in 3D? Is the compressible flow solver able to simulate in the supersonic regime? and, how can I get the drag and lift force or the shear stress in a hull using Nektar++? Thank you for your time! Best regards, Octavio A. Morales.
