boundary condition porblem..
thanks for taking the time and check my case..
for starters i had already try with symmetryPlane and below was my error
I hope you be able to help...:( :(
I had a look at your case and tried to run a few sims.
My take is that the mesh is probably the root of the issue. I tried to take things away:
- turn turbulence off;
- use upwind scheme;
- reduce residuals;
- use a potentialFoam solution;
- change the outlet boundary conditions;
- tighten solver residuals.
The following picture shows the non-physical spike of velocity after as little as 10 iterations. Sorry, but I can't help further.
First of ALl thanks a lot for the useful and intelligent pointers you gave to me..
As wih simpleFoam its not working at all.. I have used pisoFOam and still it not work.
But with pisoFoam i include the boundary cond of symmetryPlane.. so lo and behold... the FLow is being as i wanted!!!
But with pisoFoam, it takes along timeeeee to finish iterating and acheive convergence..
i am now at 20319 second and its sill going strong in iteration.. But at least its giving the required results..
Following your post: you may want to try changing:
thanks am trying it right away..
I am obtaining superb resutls with pisofoam. but WHY DOES IT TAKE SOO MUCH TIME TO ITERATE???
