Recently I was doing some research in the antarctica ice berg ,I am trying using the elmer/ice model to simulating the dynamics and thermodynamics . when I do this ,I encounter many problem,can any one give me some help?

my problem as folows :

first ,the sliding section . http://elmerfem.org/forum/viewtopic.php ... 44e6d625afas this paper say ,I encounter the same question,I do not know the differences between the two units,and I just don't know How I set the Slip Coefficient 2 and the Slip Coefficient3.

second ,when I set the two parameters as

I obtain a velocity as follows:Flow Force BC = Logical True

Normal-Tangential Velocity = Logical True

Velocity 1 = Real 0.0e0

Slip Coefficient 2 = Real 1000

Slip Coefficient 3 = Real 1000

I find the velocity is very big .I just do not know the unit of the velocity.

third,I have not sucessfully the transient simulation and every time the problem as follows

StructuredMeshMapper: >Correct Surface< in case of intersecting upper and lower surface

StructuredMeshMapper: Adjusting upper surface to maintain minimum height to: 0.1000E+01

FlowdepthSolver: Memory allocation done.

FlowdepthSolver: Gradient of -0.1000E+01 applied
