I am trying to run a flow simulation of a valve where a valve body moves in a chamber. when I gave conditions for 1d translation and ran the simulation the whole fluid domain moves ( that is the valve body moves along with the chamber as a single body). I wanted only the valve body to move within the chamber. I am not sure where I did the mistake I think it should be somewhere in assembly but not able to figure it out. I would appreciate it if somebody could help me out with this problem.
To simulate the movement of valve boides, you need to split the domain along the movement path. Also use volume remesh together with expression to handle mesh deformation during the whole process. For sure the 1d dof solver handle the speed and position of the valve body. Please contact your support to get more information about this. Thanks.
