Hi Mohammad, I think that *demo_GPU_mixer.cpp* demo does exactly what you needed. While you are looking into this demo, I just want to mention one thing to avoid confusion: in terms of controlling the mesh motion in C::GPU, the *Transform *call before *AddMesh *should only be used to "align" the mesh with its CoM before the simulation starts, so that when the mesh is loaded it is expressed in its centroid and principal frame; it should not be used to set the initial location of the mesh. Instead, like in the demo, use *ApplyMeshMotion *to control the mesh motion throughout the simulation.
Hope it helps!
