Hello!
I'm running a transient simulation with increased SMB for some sensitivity testing. The expectation is that the glacier would advance, but it ends up significantly retreating after a big speed up and thinning at the second time step.
This is a tidewater glacier, so I've set the calving rate and frontal melt rate to 0 - the glacier still retreats. I'm looking through the model setup and boundary conditions to identify what might be causing this, but starting to hit a wall.
Any advice would be greatly appreciated, thanks!
