hello dear friends
i need obtain throw distance water jet in spillway bucket, how do this?
As we know the throw distance followed from projectile law, but How do I apply this in cfx?? Do I have to use expression in cfx?
please help me

Have you completed all of the CFX tutorials?

my model is free surface, i read tuturial about free surface but unfortunately not helpful.
If you have information about this, please help me.
As far as I know, the software can not directly calculate throw distance.
thanks

I would think it unlikely that CFX cannot model the throw distance. Why do you say that?

You will need to set it up correctly to model this but it should be possible. First of all you have to think of boundary conditions and fluid properties, not projectile laws. Do some of the tutorials to see what we are talking about.

dear ghorrocks

Can not be used in software code to do that? Is it possible to code in cfx,there , In which the software can do it?
whether cfx written language fortran & c?
thanks a lot

Let me say it again but more clearly.

Yes, CFX can model the throw distance of your flow.

CFX is a commercial software package written in a combination of C and fortran, but as it is commercial you are not able to access the source code.
