AuxSubfieldsTimeDependent

Full name:

pylith.bc.AuxSubfieldsTimeDependent

Journal name:

auxfieldstimedependent

Auxiliary subfields for time-dependent boundary conditions.

The boundary conditions values have the functional form:

(168)\[\begin{equation} f(x,t) = f_0(x) + \dot{f}_1(x)(t-t_1(x)) + f_2(x)a(t-t_2(x)) \end{equation}\]

The association of these functions with the auxiliary subfields is:

\(f_0(x)\):

initial_amplitude

\(\dot{f}_1(x)\):

rate_amplitude

\(t_1(x)\):

rate_start

\(f_2(x)\):

time_history_amplitude

\(t_2(x)\):

time_history_start
