adhivenugopalan is on a distinguished road
Hi People,

I am facing problem in convergence for Eulerian multiphase model involving fuel jettisoning (fuel dumping) in external compressible flow for pressure based solver. I am able to converge the same conditions for incompresible flow. Tried reducing under relaxation factors,disabling energy equation for a while and also changing solution limits but cannot control Epsilon and turbulent viscosity .My boundary conditions are:
Dimension: 3D
Multiphase: Eulerian
Turbulence Model: K-epsilon
Domain inlet: Velocity Inlet
Jettison Boundary : mass flow inlet

Kindly Help.
