paraFoam during execution
 

Hi Foamers,

I am running my first simulations in OF and I have several questions.
The most important one is related to ParaView during execution of a case. I am running a steady state, incompressible case (an internal flow through a complex channel in laminar regime), so I am using simpleFoam for this stage. I write data for every 10 iterations and when I launch ParaView to see how the solution in changing with iterations, it looks like the solution (contours of pressure and velocity) loses the physical meaning (for example I expected velocities of about 5 m/s and in contours of velocity and the legend shows zones with velocities of 1000 m/s). Obviously, for a fast plot of residuals I see that the solution is not converged yet. In FLUENT if you stop simulation before it´s converged (and of course if everything is going well), you see magnitudes close to the real solution, more accurate with the progress of iterations. Is that true for OpenFOAM? It´s to say, is it normal that ParaView shows these values at this step (400 iterations done) or have I to wait thousands of iterations and low residuals values to take in count the contour graphics at each iteration step?

Sorry for my bad English, I hope everyone have understood what I want to explain.

Thanks in advance for the answers of the users!
