Hi everbody,
I am not very keen in setting up Ansys Pre with the right configuration data like time step and duration.
I read that its quite common to calculate such problems with discrete equations of first order in accuracy.
Can anybody help me with the settings or with advice?
greetings

I do not understand your question. If you are asking how do you implement first order time and space schemes, then this can be set under the solver tab.

I want to simulate a stationary incoming flow to a truncated cone with supersonic inlet. I read that for stationary incoming flow with supersonic speed there is a disadvantage in the way of solving the differential equations (eliptical/hyperbolical). So its better to solve while using transient flow settings (just hyperbolic). But I am just interessted in the stationary solution of the problem so its suficient to use the equtions of first order. But I have no idea how to set up these things like time step and so on..
