ActuallyExplicitEuler

This time integrator is an implementation of forward/explicit Euler based on ExplicitTimeIntegrator, which avoids a nonlinear solve.

Input Parameters

solve_typeconsistentThe way to solve the system. A 'consistent' solve uses the full mass matrix and actually needs to use a linear solver to solve the problem. 'lumped' uses a lumped mass matrix with a simple inversion - incredibly fast but may be less accurate. 'lump_preconditioned' uses the lumped mass matrix as a preconditioner for the 'consistent' solve
Default:consistent
C++ Type:MooseEnum
Unit:(no unit assumed)
Options:consistent, lumped, lump_preconditioned
Controllable:No

use_constant_massFalseIf set to true, will only compute the mass matrix in the first time step, and keep using it throughout the simulation.
