transient residual error
 

Dear All

I tried to run my case with a transient solver (rhoPimpleFoam).

with the original case from OpenFOAM 1.5 tutorial (angledDuct), i can plot easily the residual error of Ux Uy Uz.


but when i tried to run with my 3D case, i could not plot the residual error over times, due to each of log files only contain 1 value.


example :


original case from OpenFOAM (angledDuct, 3D case):

UxFinalRes_0


1 0.0381702
2 3.24059e-05
3 1.47824e-06
4 4.25961e-05
5 2.34306e-05
6 8.58533e-06
7 8.629e-06
8 8.71595e-06
9 5.03757e-06
10 3.01017e-06







my case (3D) case:


UxFinalRes_0


1 0.0653521







whats wrong with the OpenFOAM ?


i have checked my controlDict for both cases, and they are similar.




does somebody know why this happen? how to solve this problem?

please, i really need some help.



Thanks
