transient analysis
 
Hi all,

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.

Try to change arbitary sliding mesh to regular sliding mesh,
