Hello everyone,

Using snappyHexMesh, I discretized my gas turbine model to simulate using pisoFoam (unsteady compressible solver). Initially I am going with laminar flow to ensure my initial case setups like boundary conditions and other parameters are appropriate. The case runs smooth and good but the convergence happens pretty fast at very first time step.

I rechecked my boundary conditions, its all right. Internal field of velocity is set to (0 0 0) but at very first time step of 10^(-4), the post processing results shows increase in appropriate velocity all over the complete domain (below attached image for t =10^(-4)). So for increase in time, the velocity doesn't change anymore. The flow doesn't move gradually from the inlet to the outlet (as like motor bike example case). I even checked with high refined mesh and very less time step of 10^(-6) second.



AM I missing something ? Can someone correct me where I am wrong.
Thank you
