More on this subject comes from Lee Bindeman: “When using a vectorized subroutine (i.e. The storage location is dependent on a number of factors such as whether the subroutine is vectorized or nonvectorized, whethere the elements are shells or solids, etc.
In pre-970 versions of LS-DYNA, the 1st history variable in the umat subroutine won’t be stored as history var#1 in the d3plot database. Clearly in that situation, the user knows what the extra history variables are. Extra history variables can be employed to great benefit in the case of a user-defined material routine. A time history plot of the extra history variable may then be created by selecting History > Scalar. Extra history variables, when written to the d3plot database, (see NEIPH and NEIPS in *DATABASE_EXTENT_BINARY) may be fringed using LS-POST by selecting Fcomp > Misc > history var#n.
