ExplicitEuler
Time integration using the explicit Euler method.
The explicit Euler method is only first-order accurate in time.
Description
With , the vector of nonlinear variables, and , a nonlinear operator, we write the PDE of interest as:
Using for the current time step, and for the previous step, the explicit Euler method can be written:
This method can be expressed as a Runge-Kutta method with the following Butcher Tableau:
commentnote
The ActuallyExplicitEuler implements the same algorithm but without forming the non linear system, making it faster and use less memory.
warningwarning
All kernels except time-(derivative)-kernels should have the parameter implicit=false to use this time integrator.
