Hey, Guys. anyone can solve my problem? Thanks.
In my model, there is a tank which is full of water,and the height of tank is h. I put some salt into the water. The distribution of salt is not uniform, so the concentrations of salt in the different heights(0-h) is also different. I want to use a equation in CFX source, and the equation is S=H*C.
C is the mass fraction of salt, and I can use mf.salt to describe it.
But how to describe the "H", H is the height from tank bottom to tank top. "H" is the integration process. Can I use the Expression to describe this H?

If the bottom of the tank is at z=0, then H=z. Isn't that obvious?
