Default UDF for simulating the suction feeding in a fish

moh.hefny is on a distinguished road
I would like to simulate the suction feeding in a fish. To that end, I created the geometry of a fish in a tank (2D). I need to modify the mouse void (buccal cavity) during the simulation so that the fish sucks water in. I assume I need a UDF to move the boundary during the simulation (dynamic mesh).

Unfortunate my knowledge in this part is less than basic. Could someone be so kind as to assist me to perform this simulation.

Thank you in advance.

Best regards,
