Here is the call graph for this function:

evaluate_implicit()

subroutine mod_advance::evaluate_implicit	(	double precision, intent(in)	qtC,
		type(state), dimension(max_blocks), target	psa
	)

Evaluate Implicit part in place, i.e. psa==>F_im(psa)

Parameters

	psa	Compute implicit part from this state and update it
[in]	qtc	psa at this time level

Definition at line 600 of file mod_advance.t.

subroutine mod_advance::global_implicit_update	(	double precision, intent(in)	dtfactor,
		double precision, intent(in)	qdt,
		double precision, intent(in)	qtC,
		type(state), dimension(max_blocks), target	psa,
		type(state), dimension(max_blocks), target	psb
	)

Implicit global update step within IMEX schemes, advance psa=psb+dtfactor*qdt*F_im(psa)

Parameters

	psa	Compute implicit part from this state and update it
	psb	Will be unchanged, as on entry
[in]	qdt	overall time step dt
[in]	qtc	Both states psa and psb at this time level
[in]	dtfactor	Advance psa=psb+dtfactor*qdt*F_im(psa)

First copy all variables from a to b, this is necessary to account for

Definition at line 571 of file mod_advance.t.

Here is the call graph for this function:

process()

subroutine, public mod_advance::process	(	integer, intent(in)	iit,
		double precision, intent(in)	qt
	)

process is a user entry in time loop, before output and advance allows to modify solution, add extra variables, etc. Warning: CFL dt already determined (and is not recomputed)!

Definition at line 739 of file mod_advance.t.

Here is the call graph for this function:

process_advanced()

subroutine, public mod_advance::process_advanced	(	integer, intent(in)	iit,
		double precision, intent(in)	qt
	)

process_advanced is user entry in time loop, just after advance allows to modify solution, add extra variables, etc. added for handling two-way coupled PIC-MHD Warning: w is now at global_time^(n+1), global time and iteration at global_time^n, it^n
