Power house intersected by a fault
The figure shows the slip on the fault.
In this example the powerhouse is constructed with FF (fictitious force) elements and the fault is constructed with DD (displacement discontinuity) elements. The DD elements are filled with an elasto-plastic gouge material that yields according to the frictional strength Mohr-Coulomb criterion.
838 surfaces were used to describe this problem. Map3D subsequently discretized the model into 5236 boundary elements.
