Integrator Reset Functions

Integrator Reset Functions

Table 14 lists the integrator reset functions. These functions allow you to reset the integrator so integration may start over, or install a new ODE or Butcher Table.

Table 14 Integrator Reset Functions.

Usage

pInteg-Reset();

Arguments

None.

Return Value

None.

Notes

This function causes the integrator to reset for another integration run. All of the counters and output variables are returned to their initial values. All initial conditions, step size selection methods, etc., will be left at the values they have been set with the functions detailed in the previous sections. This routine also calls the Reset( function defined in the ODE, if there is one.

Usage

pInteg->InstallNewBT(pBT);

Arguments

Return Value

None.

Notes

This function installs a new Butcher Table object in the integrator. It calls Reset( to reset the integrator

Usage

pInteg->InstallNewODE(pODE);

Arguments

Return Value

None.

Notes

This function installs a new ODE object in the integrator. It calls Reset( to reset the integrator.

Usage

pInteg->UpdateODE();

pInteg->UpdateODE(y0);

pInteg->UpdateODE(y0, h0);

pInteg->UpdateODE(y0, h0, atol);

pInteg->UpdateODE(y0, h0, atol, rtol);

Arguments

Return Value

None.

Notes

This function resets the initial values of the ODE object. It calls Reset( to reset the integrator. This function is useful for preparing an ODE for a new Monte Carlo run or supplying input after reading data from an input file.
