Non viscous flow
 

Hello, I can not get a stabilized solution for a certain flow configuration (I ran a transient simulation for 15 seconds on a 4500000 mesh elements and the solution is still varying). To investigate if the fluctuations are physical or numerical I would like to run the exact same calculation except that I would like to specify the flow as non viscous. However I can not find the option to select an Eulerian flow. Could anybody help me ?

Thank you
