Dear FOAMers

I am simulating an underwater fountain with two different water densities. The fountain pipe is 30 cm in height and is located at the center of the tank.

In order to fill the pipe with heavy water, I used a pipe with an inner diameter of 8 mm but an outer square cross-section of 16 mm X 16 mm so that I could fill it with the setFields by defining a box. Although in doing so, I went a bit away from our physical experimental conditions (since the actual pipe has 8 mm inside diameter and 10 mm outside diameter).

I actually need a circular pipe, but the problem is that I don't know how to fill it with heavy water using setFields or any other technique.

Kindly help me solve this issue. Much appreciation
