My problem involves, free surface and moving mesh. But when I try to simulate the problem it is coming out saying run is unstable after some iterations. I have tried follwing to stabilize the problem.
1. reduced the time step in order of E-3.
2. tried to simulate one phenomina at a time, like free surface-without moving mesh and moving mesh-without free surface.
3. try mapping steady state initial conditions (smap)[steady state it works very fine]
In all above I am unsuccessful. Can anybody guide me with some clue.
Thanks a lot.
Re: transient analysis
Try to change arbitary sliding mesh to regular sliding mesh,
