Detailed Description

This is sibc1st. The numproc solves the electric field vector wave equation in 3-dimensional space which is truncated by a cavity wall of finite thickness, thereby causing ohmic loss in the cavity boundary; the surface impedance is approximated as being constant over frequency, instead of varying as determined by the skin effect.

Function Documentation

INT InitSIBC1st

(

void

)

This function is used in the main program acheron3dlgm for checking the sibc1st numproc into the UG framework.

USING_UG_NAMESPACE static USING_UGDIM_NAMESPACE INT SIBC1stInit	(	NP_BASE *	base,
		INT	argc,
		char **	argv
	)			[static]

SIBC1stInit - initialization funtion for the NUMPROC 'NP_SIBC1ST_SOLVER'; the function is called when npinit <sibc1st> is executed in the UG script

assignment of the function (1) read all vector and matric descriptors and link the variable names of the UG script with the pointers to said structures stored within UG. (2) assemble global matrices TMAT, SMAT and RMAT, if losses shall be considered in the computation

calling syntax for npinit <SIBC1st> is:

npinit <sibc1st> $EP efldp $EN efldpn $EM efldm $RHS rhs $TMAT tmat $RMAT rmat $SMAT smat $DT 10.0e-12;

where $EP efldp -> VECDATA_DESC structure for electric field along the edges of the element at time t_(n+1) $EN efldn -> VECDATA_DESC structure for electric field along the edges of the element at time t_(n) $EM efldm -> VECDATA_DESC structure for electric field along the edges of the element at time t_(n-1)

$RHS rhs -> VECDATA_DESC structure for the right-hand side of the linear system to be solved for

$TMAT tmat -> MATDATA_DESC structure for matrix containing the T matrix $RMAT rmat -> MATDATA_DESC structure for matrix containing the R matrix (losses) $SMAT smat -> MATDATA_DESC structure for matrix containing the S matrix $PRMAT smat -> MATDATA_DESC structure for matrix containing the PR resistive sibc matrix $PLMAT smat -> MATDATA_DESC structure for matrix containing the PL inductive sibc matrix

$DT 1.0e-12 -> DOUBLE value for the time step in the explicit scheme

now, compute surface resistance and surface inductance
