How calculate simulation duration - CFX Solver
 
Hello

Is there a way to calculate the simulation session time for running? (until the Solver process is done...)
Example: Iteration Numbers * ...*...*= xxxx min

Thanks

see the out file for simulation start time and finish time.

Hehe, i mean in advance :-)

This is very difficult to estimate with any accuracy in general. If you have a number of similar simulations you might be able to get a feel for it but if a new simulation pops up it will all change.

There are many levels of convergence required for a CFD simulation and getting estimates in advance of how quickly they converge is just about impossible.
