Hi, I try to access solid neighbour cells of fluid cells by using parameter 'LQ' at the interface. Whenever those fluid cells call for the adjacent solid cells, it returns the negative values of solid cell numbers.But i suppose this are the interface boundary numbers and not solid cell numbers(they should be positive numbers).How to access the solid cell numbers. Thanks for your time. regards Thiyaga.

you need to attend the advanced training course on user coding for this.

I guess you're using star 3.26, otherwise you wouldn't be using LQ, but anyway it's best to ask support, they will help you.

btw. do not forget, the number you get is not a prostar cell number.

well, not much of a help, is this post... matej
