f_

)

Calculate the lumped variables.

This subroutine calculates the lumped variables f_ (left-hand side of the equations of the model).

Parameters

Here is the caller graph for this function:

subroutine solver_module::marching	(	real*8, dimension(:), intent(in)	fold,
		real*8, dimension(:), intent(out)	fnew,
		real*8, dimension(:), intent(in)	rate
	)

Marching s one step.

This subroutine update the solution of the model from s to s+ds as fnew=fold+ds*rate.

Parameters

[in]	fold	old lumped variables
[in]	rate	rate of change of the lumped variables
[out]	fnew	new lumped variables
