Hey everyone,

We know that Lattice Boltzmann method is used to study many classical aspects of fluid flow including phase change. But I was wondering how we can use LBM in form of UDF in ANSYS FLUENT to solve any fluid flow cases.

If anyone has any idea or any thoughts about it, YOU ARE MOST WELCOME TO SHARE.

You can code anything in a UDF, so in theory you can make LB solver in a UDF. But why would you? If you can do that, it is smarter to make a stand-alone LB solver...

So I would ask back: why in Fluent? Fluent is a finite volume solver, not LB. Which part of Fluent do you hope to use?
"The UDF library you are trying to load (libudf) is not compiled for parallel use on the current platform" is NOT the error after compiling. It is the error after loading. To see compiler errors, look at your screen after you click "build".
