Hi all,
I went for an overkill!! And I guess some people will disagree with my actions. Here is a summary of my systematic actions (done one at atime). -Refined the grids -doubled the default inner iterations -Used courant no of 5 and backward quadratic time scheme (as recommended by Jan, Thanks). Then all the above set with.. -24,000 Total iterations!!! (that is NSTEP=600, MAXIT=40, DT=0.002sec, 60 impeller rev.) Convergence seems better (It is still going on since Saturday 3.00pm, it is now 5.10 pm Monday). As I had mentioned before, convergence is just one of the indicator of a good solution. I will inject my tracer and see what comes out now. I will filter later some of the un necessary loads I have given my machine. Many thanks John, Jan and KubaB. I will be back again with the tracer proper, after such a long suspension of the same. regards nyatoto |
