v4.0) Laminar flow convergence problem

Please login with a confirmed email address before reporting spam


I want to add volume force(gravity) at laminar flow physics.

however, there is convergence problem, even though I set the iteration value up to 25000 at constant damping factor

the only difference between below 2 files is volume force.

But I don't know why one is solved and the other is not.

Please give me your help
