Turbulence model of hydraulic valve
Posted Oct 15, 2012, 9:13 AM EDT Version 4.3 3 Replies
I really hope you can help me with this:-)
I'm currently trying to simulate a flow of hydraulic oil through a valve however, I keep getting the following error:
Failed to find a solution.
In segregated group 1:
Divergence of the linear iterations.
Returned solution is not converged.
I'm relatively new at using Comsol but this forum has giving me a lot of information and I've solved many of my previous poblems using your answers although I couldn really find anything about my current problem. I've tried to fix the stated problem by increasing the Factor of error estimate which did'n do anything.
It's a rather simple geometry at 220x160x140 [mm] and Im having enough elements for the boundary layer mesh to be without errors or problems which leaves me at 271206 degrees of freedom.
I've included the convergence plot.
