Hi everyone,

I am doing some case which is a solid(wedge) slides down through a slope, and get into water.

Tthe OF version I have are OF 4.1 and OF v1812 ,and the solver I use is "olaDyMFlow" which is probaly same as InterDyMFoam.

And the case I want to establish refer to the paper "Runup and rundown generated by three-dimensional sliding masses" .

The problem I am facing is mesh displacement causing the simulation crash.
Which I realize is the dynamic mesh limits that the cell can not be extruded to small or deform to big.
And I don't know how to improve it anyway.

I attatch my case here and I hope someone can take a look, I will be appreciate that.

Best,

James
