dear forums and supporters,
 
i am working in code-Saturn for past 3 months on Lagrangian particle tracking.........
please can any body tell me how to have different particle size at the same point of injection.......
and when the particle numbers are increased the solver is taking the same time to remove for 1000 , 10000 ,50000 particles..
 
thanking you in advance ....... please help me out as soon as possible..
with regards

Hello,
To use particles of different size, search for "particle classes" in the user documentation PDF file.

For Code_Saturne, an inlet pressure means an outlet with a backflow. So, for an inlet pressure you should select an outlet with  a fixed value for the pressure in usclim.f90.

Hi Alex

I saw the usclim.f90 file and i am fully confused with that...........

can you please help out by providing the steps to incorporate the pressure inlet.

As of now i am using Code-Saturne GUI.
