+# Sample time step group definition file for TECTON. This file

+# group number 0 and must always be defined. Some of the parameters
+# have no meaning for the elastic solution but they are defined
+# anyway. In the fortran code, each of the parameters (other than n)
+# is stored in a separate array of dimension nintg+1, where nintg
+# is the number of time step groups. The definitions are as follows:
+#
+# n = time step group number. The elastic solution
+# corresponds to group number 0, and must always be
+# defined.
+# maxstp = the number of steps in the group (this is always 1 for
+# the elastic solution).
+# delt = time step size. This is a real value with units of
+# time.
+# alfa = amount of implicitness. This is a real dimensionless
+# parameter with values that can range from 0.0 (fully
+# explicit) to 1.0 (fully implicit). The value is
+# generally set to 0.5.
+# maxit = maximum number of equilibrium iterations before stiffness
+# matrix is reformed.
+# ntdinit= number of time steps between initial reformation of
+# stiffness matrix (before any iterations). A negative
+# value indicates that reformation should occur only once
+# for the first step in the group. A value of zero indicates
+# that reformation should never occur.
+# lgdef = large deformation solution flag. This is an integer
+# parameter with 3 possible values:
+# 0: linear strain
+# 1: large strain, but use only the linear contribution
+# to the stiffness matrix. This sometimes gives
+# better convergence.
+# 2: large strain using the nonlinear contribution to the
+# stiffness matrix.
+#
+# Convergence criteria for the nonlinear iterative solution:
+#
+# utol = convergence tolerance for displacements. This is a
+# dimensionless real value.
+# ftol = convergence tolerance for forces. This is a
+# dimensionless real value.
+# etol = convergence tolerance for energy. This is a
+# dimensionless real value.
+# itmax = maximum number of equilibrium iterations. This is an
+# integer quantity.
+#
+# Note that the convergence criteria defined below are appropriate for
+# a linear elastic problem. The values would be much different for a
+# nonlinear or time-dependent problem.

+# The only parameter in this list requiring units is the time step
