\( \int u dS \)

field_probe_eval()

subroutine field_probe_eval	(	class(field_probe), intent(inout)	self,
		real(r8), dimension(:,:), intent(inout)	vals )

Evalute field at all probe locations.

Parameters

[in,out]

vals

Fields at all probe locations [3,npts]

field_probe_save()

subroutine field_probe_save	(	class(field_probe), intent(inout)	self,
		real(r8), intent(in)	time )

Sample and save the result to the history file.

Parameters

time

Time of signal sample

subroutine field_probe_setup	(	class(field_probe), intent(inout)	self,
		integer(i4), intent(inout)	npts,
		real(r8), dimension(:,:), intent(in), optional	pts,
		character(len=*), intent(in), optional	filename )

filename

Filename for history file

flux_probe_eval()
