https://communities.bentley.com/products/geotech-analysis/f/forum/230157/rotation-volume-elementsHello Everyone, As you may see below I have a volume (grey) with soil elements with a very high stiffness, hence a volume acting as a rigid body, laying in a soft clay layer. Does anyone have any trick to not allow rotation of the grey volume?
