maxIterations depends on minTimestep
In the constructor of CalculationController
, eps
is used to instantiate itmax
as an increased value from time.maxIterations
. However, eps
is instantiated from dtmin
, which can cause trouble if the latter is set too high. Specifically, itmax
was decreased below itmin
, which caused the solver to fail.
Solution: Use rounding in calcIterations
, save iterations as integers, remove eps
from itmax
constructor.
