[Geoqus] Erosion and surface modification with ABAQUS

[Kasper Fischer]

Hi Peter Connolly,

you wrote that you would include a 'passive' step to minimise the 
influence (on element stress?) when moving nodes with the *BOUNDARY 
option. Can You please explain what you mean with a 'passive' step? I am 
very interested how this works, because it seems that this would be a 
more elegant way then the way I went.

Thanks

Kasper
