Hi all,

I have a sphere inside a cylindrical flow domain of some diameter. The flow domain will be having velocity inlet on one side and pressure outlet on other side.

QUESTION:

To the sphere at the center I need to assign some mass say 1 kg. Is there any way of assigning "mass" to the sphere using UDF?

I know that I can patch some mass after initialization. But since I am going to change that as the time goes by, I need to assign "mass" only with UDF.

To be specific, what type of "macro" I should use to provide mass(like DEFINE_SOURCE or any other)??

Any help is of great use for me.

Thanks in advance,
