method

BaseAlgorithm.one_time_step_local(f, fnew, m)¶

Return symbolic expression which makes one time step of LBM algorithm:

• transport

• compute the moments from the distributed functions

• source terms with dt/2 (with the moments)

• relaxation (with the moments)

• source terms with dt/2 (with the moments)

• compute the new distributed functions from the moments

Parameters:

fSymPy Matrix

indexed objects for the old distributed functions

fnewSymPy Matrix

indexed objects for the new distributed functions

mSymPy Matrix

indexed objects for the moments
