I have just started working on Ansys, and need to perform a simple translation motion. In the attached geometry, my requirement is that the piston moves from the point A to point B, accelerating uniformly till the mid point and then de-accelarating to zero velocity when it reaches point B. Can anyone help me regarding the procedure on how to do it, or give a clue on how to start?? The piston is moving a multi-phase liquid, comprising of liquid and small particles of a metal.

Define the motion as a displacement versus time. Then use moving mesh and apply the displacement to the piston face.

There are tutorials which come with CFX on how to set up moving mesh simulations.

The tutorials come with CFX. Have a look in the tutorials manual.
