simpleFoam, Solving Pressure problem
Join Date: Oct 2013

Im currently running a case using simpleFoam to analyse the flow over a helicopter fuselage.
There seems to be an issue when solving for pressure.
For example the initial residual =1 but the final residual also =1. Clearly there is something wrong and it takes a VERY long time to solve.
I have mainly used only simpleFoam and havent had this kind of issue before. Does anyone know what could be causing this? Could be something very simple?
Any advice would be appreciated.

Can you give more details about your case (i.e. boundary conditions)?

I have one question about paraView window 3.12.0. It is working properly, but the Apply icon is not activated?
Whats the problem?
What shall I do to activate it?

James, that sounds like your pressure equation doesn't converge and takes the maximum number of iterations ("maxIter" in fvSolution) to try ("VERY long time to solve."). Did you change something in your fvSolution file?
