Hi Dear Friends,
I have simulated the natural convection in annular circular cylinder with LBM; I had met this forum nearly! I get confused when read the posts about LBM unit and other posts in open LB!! My code is in FORTRAN and can’t understand openLB codes well, I have 2 problems in my simulation!!!
One that how to implement curve boundary for cylinder isothermal wall!
And another is can I run in Cartesian coordinate for this problem? I have got good results in isotherms and streamline with Cartesian but not in Nu number on walls!!
This simulation is part of my Ms Final project and I need your help necessarily!!
Please help me!
Best regard
