NLTRD
Computes transient nonlinear analysis solution matrices and tables
NOTIME Output-integer-default=0. Time out flag. Set to 1 if there is no time left
for further iterations but enough time to perform data recovery.
MAXLP Input-integer-default=0. Maximum limit allowed for element relaxation
iteration and the material subincrement processes.
UNUSED17 Input-integer-default=0. Unused.
UNUSED18 Input-integer-default=0. Unused.
UNUSED19 Input-integer-default=0. Unused.
TABS Input-real-default=0.0. Absolute temperature conversion. For example,
set to 273.16 when specifying temperatures in Celsius or 459.69 in
Fahrenheit.
LANGLE Input-integer-default=1. Large rotation calculation method:
1 Gimbal angle
2 Rotation vector
Remarks:
1. NLTRD supports only METHOD="AUTO" and "TSTEP" on the TSTEPNL Bulk
Data entry. NLTRD2 supports only METHOD="ADAPT".
2. NLTRD does not support heat transfer, slideline contact, or shell normals. Use
NLTRD2.
3. ULNT contains only displacement and velocity vectors at converged time steps
during the direct integration. However, upon completion of the subcase it also
contains acceleration for the output time steps.
