Hi,
I am running the LES with same case file and with same parameters one on local machine with 8gb memory, intel quad core with ansys 12 installed, the other machine being a high performance cluster with 8gb shared memory with 4 processors per node, the processors are amd opteron 8378.

I am seeing that the the case being run locally shows about 40 in the time/iter column, and the hpc one show about 2 mins.

Is there a major difference between the two versions of fluent?

Thanks,
vishwa

Also, I have pasted here at the output at the command prompt while the simulation is running. Like I have mentioned, I am running a LES simulation using NITA (PISO). My question is why is it that I see the continuity, x-velocity, y and z-velocity residual values for some time steps and not the others..
