Anchor End Points
Introducing pre-stressed anchors into the soil may lead to plastic deformation of the soil in the vicinity of the anchor head or root - the analysis then often fails to converge.
In such a case we recommend the following modifications of the original input:
- to place a beam element under the anchor head (this results into a better transition of load into the soil),
- to place the anchor root into a sufficiently stiff soil (use the elastic or modified elastic material model for the soil layer around the anchor).
