# Provide ground movement calculation for re-entrant corners.

Two current ideas:

a simple proportioning of the contributions to a point's displacements based on how many sides contribute, if 2, then each 50%, if 3, then each 30% etc. But may also need consideration for the angle. Simple geometrical solution (with warning) if nothing better received.

a geometric solution which could be coded and compared to finite element analysis.

Same ideas can apply to changes in ground movement curve between one wall and another.
