PETSc version 3.17.5

TSMonitor

Runs all user-provided monitor routines set using TSMonitorSet()

#include "petscts.h"  
PetscErrorCode TSMonitor(TS ts,PetscInt step,PetscReal ptime,Vec u)

Collective on TS

	ts	- time stepping context obtained from TSCreate()
	step	- step number that has just completed
	ptime	- model time of the state
	u	- state at the current model time

TSMonitor() is typically used automatically within the time stepping implementations. Users would almost never call this routine directly.

A step of -1 indicates that the monitor is being called on a solution obtained by interpolating from computed solutions
