Section 6.2 - Incremental Updating of Mass Matrix LATDYN uses a consistent mass formulation in its solution procedure. ... If rigid members, MTYPE=3 in the MATPROP command, are used, the mass matrix will need to be updated. ... when any rigid member rotates through the specified incremental angle since the previous update, independent of what caused the previous update. ... The sample problem of Section 6.1 illustrates the effect of these updates on solution accuracy.
