[solver-dual-time-integrator-multip]

Parameterises multi-p for dual time-stepping with

  1. pseudo-dt-fact — factor by which the pseudo time-step size changes between multi-p levels:

    float

  2. cycle — nature of a single multi-p cycle:

    [(order, nsteps), (order, nsteps), ... (order, nsteps)]

    where order in the first and last bracketed pair must be the overall polynomial order used for the simulation, order can only change by one between subsequent bracketed pairs, and nsteps is a non-negative rational number.

Example:

[solver-dual-time-integrator-multip]
pseudo-dt-fact = 2.3
cycle = [(3, 0.1), (2, 0.1), (1, 0.2), (0, 1.4), (1, 1.1), (2, 1.1), (3, 4.5)]

Used in the following Examples:
