iterateTimeStep#

Definition
bool ProblemTrio::iterateTimeStep(bool &converged) override
Brief description

In the case solveTimeStep uses an iterative process, this method executes a single iteration.

Detailed description

It is thus possible to modify the given fields between iterations. converged is set to true if the process has converged, ie if the unknown fields are solution to the problem on the next time step. Otherwise converged is set to false. The return value indicates if the convergence process behaves normally. If false, the ProblemTrio wishes to abort the time step resolution.

resetTime#

Definition
void ProblemTrio::resetTime(double time) override
Brief description

Reset the current time of the Problem to a given value.

Detailed description

New in version 2 of ICoCo . Particularly useful for the initialization of complex transients: the starting point of the transient of interest is computed first, the time is reset to 0, and then the actual transient of interest starts with proper initial conditions, and global time 0. Can be called outside the TIME_STEP_DEFINED context (see Problem documentation).
