mpoint locking-adjustment command

Syntax

mpoint locking-adjustment b

Set mitigation of volumetric locking (off by default). Volumetric locking mitigation is achieved by a cell-centered, volumetric-weighted average of the trace of the mpoint velocity gradient for each background mesh cell. The resulting value is used as the velocity gradient of the mpoints falling within each cell. This updated value of the mpoint velocity gradient is used to compute the mpoint stress.
