Hello, guys,

I am a new one for Openlb.

As we know, the equilibrium function is very important in the LBM

But I cannot find the definition and computation about equilibrium function in the of codes.Where is it?

And the “collide() member function” in olb::BlockLattice2D<T,Lattice> class, why is “virtual void collide() =0;” , or is it return zero?

I want to familiar with the olb code quickly, could someone give me some advice about how and what I should do while I face to so many codes?

Thanks.
