Elastodynamics#
This formulation solves the momentum balance equations as described in hyperelasticity. The dynamic example uses the PETSc Timestepper (TS) object to manage timestepping.
Specifically, Ratel uses the Generalized-Alpha method for second order systems (TSALPHA2
) to solve the second order system of equations given by the momentum balance.
More information on the PETSc TSALPHA2
time stepper can be found in the PETSc documentation.
