Dear Sir/Madam,
I am recently looking through the Heat transfer API code and a question comes to my mind.
In the API code, we usually specify element1 and element2 and then perform the subsequent operations.
However, I was just wondering if there is any function to determine the number of particles in a certain direction.
For example, in the following figure, there are 4 columns of particles, each with 3 particles. What function can be used to determine that the number of particles along the y-direction is 3?

Kind regards,
Chao
