Error Code 111 Plaxis -

in PLAXIS is a frequent calculation error that signals a "Soil body collapse" combined with a failure to reach the specified accuracy in the final calculation step. It essentially combines the implications of Error 101 (soil failure detected) and Error 110 (accuracy condition not met), indicating that your model has reached a physical geotechnical limit or has numerical instability that prevents a stable solution.
