how to run transisent flow in acusolve 2013?

Recommended Posts

The turbulence models all work for either steady or transient flows.  You'll need to determine which model to use for your particular application, but it will not depend on whether it's steady or transient.  (However, DES/LES would apply only to transient flows.)

Ok . Now i'm going to try with 2017 version  .  i have 2 questions  mentioned it below.

 

 had a doubt , is their anything i have to look into while running transient flow analysis?

and also do i need to change the steady flow to transient?

While running transient flow, check the nodal outputs and set them to a reasonable frequency (Default is 1000). I typically use 10 or 100 depending upon the case.

 

Also change the the initial time increment in Auto Solution Strategy to 0.1 sec or whatever might be suitable for your case.
