Auxiliary Functions

basicTime :: Specs m -> Int -> Int -> Double Source

Returns a simulation time for the integration point specified by the specs, iteration and phase.

integIterationBnds :: Specs m -> (Int, Int) Source

Returns the first and last integration iterations.

integIterationHiBnd :: Specs m -> Int Source

Returns the last integration iteration.

integIterationLoBnd :: Specs m -> Int Source

Returns the first integration iteration, i.e. zero.

integPhaseBnds :: Specs m -> (Int, Int) Source

Returns the first and last integration phases.

integPhaseHiBnd :: Specs m -> Int Source

Returns the last integration phase, 0 for Euler's method, 1 for RK2 and 3 for RK4.

integPhaseLoBnd :: Specs m -> Int Source

Returns the first integration phase, i.e. zero.

integTimes :: Specs m -> [Double] Source

Return the integration time values.
