Solidworks flow simulation vs fluent3/31/2024 ![]() ![]() A travel is the number of iterations it takes for a disturbance to fully propagate across the domain. So I think your question is how does it know when this has happened? Well, if you do nothing it has preset termination criteria for given problem types – like 4 “travels” is the default. Rather, for a (quasi) steady state solution (they don’t call it fluid dynamics for nothing) the program runs till the (typically) impulsive start-up has died out and it gets more or less “steady” (not varying much in time). ![]() This comment from Bill McEachern I regard as worthwhile to quote in length:įS runs the time averaged formulation of the Navier Stokes equations which means it essentially does a transient analysis (time explicit) solution so there is no real “converging” going on. I believe it worthwhile to discuss the concept of convergence in this scenario. We have discussed that the solver’s stop conditions must be defined before the actual solving process could proceed. It was originally planned that this series should be only of two posts’ length, however I have decided that the solving process must be elaborated as appropriate and, therefore, the result analysis part will be presented in part 3. This part of the series is dedicated to the preparation of the solving process, and the actual solving process. ![]() In the previous part we have illustrated and discussed the basic set up process for a SOLIDWORKS Flow Simulation CFD project. ![]()
