Fine cells on both sides of the wall and through the excavation depth. Cells coarsen locally away from the wall and below the toe; fine rows no longer span the whole domain. Enter 0 for uniform meshing.
Enter 0 to follow soil edges, including midside nodes for Q8 and T6. With Frictional wall contact, a positive value refines the wall separately and interpolates contact along the soil edges. Soil spacing is unchanged. Mesh settings are saved when the model is exported.
Analysis uses native factorisation and local mesh grading. Your selected mesh is retained; failed analyses never launch automatic mesh retries. Check mesh sensitivity explicitly compares at most three meshes within 30 seconds and retains your original model and results. Cancel stops server computation.
Drained Mohr-Coulomb or Undrained B continuum; prescribed hydrostatic groundwater; elastic wall with bonded or frictional contact; compression-only struts and tension-only anchors. Frictional contacts permit opening and sliding. Independent wall refinement requires Frictional mode. Initial equilibrium generates no excess pore pressure; seepage, consolidation, anchor bonded-zone interaction and prestress losses are not modelled. Check soil and wall mesh sensitivity separately.
