CFX new user, problem with solver and PRE settings
 
Hello friends, here i have some questions. 1. On what basis we have to select time step, i.e., auto time scale, physical time scale and local time scale factor ? 2. For which type of problems resolution scheme will be ok ? 3. On what basis we have to decide whether we have to go for medium 5% turbulence or we have to go for 10% or less than 1% ?

4. (a POST settings related qstn)How to create a plane in a quarter cut cylinder ? Many thanks. PLZ reply as early as possible

Your questions are too broad. Have a read thru the user manual first.

3.depends on your problem.... Sometimes turbulence condition doesn't affect the solution much. If you have experimental data, just use it!

4.a couples of ways to do that...look for icon above the view window. You have to know where to put this plane in the domain (ie. location of this plane)
