Hi,
I am new to comsol. I am trying to simulate laminar flow between two plates. In my model upper plate is moving with a constant velocity and lower plate is stationary and also it has a rectangle step in middle. Inlet and outlet boundary conditions are of zero ambient pressure. I have drawn the pressure plots, in the plot pressure has developed symmetrically i.e. half of the length pressure is positive and half of the length pressure is negative.
But, I want only positive pressure half of the length and negative pressure should be zero.
So, how do I make negative pressure zero over the other half of the length?
Which boundary condition shell I use for this purpose?
Thank you.
