Variables Automatically Set Correctly

Specific variables are used by Feko to set/estimate memory blocks. These variables should generally not be set by the user since PREFEKO estimates the variables correctly.

CAUTION:
Only adjust the variables below if an explicit error message for these variables occurs.
maxanr
The maximum number of sources.
maxapo
The size of the memory block that is used to save the coefficients in the physical optics approximation. For maxapo=0 the necessary amount will be dynamically allocated.
maxarang
The maximum number of $\vartheta$ or $\phi$ angles used with the AR card (excitation by a point source with a specified radiation pattern).
maxarpat
The maximum number of radiation pattern excitations (AR card) allowed simultaneously.
maxbsobnr
To accelerate the ray path search with PO the area under consideration is divided into boxes. Information pertaining to which box contains which object must be stored. A field of size maxbsobnr is used in this case.
maxcolayer
The maximum number of layers on a CO card which implements thin dielectric sheets.
maxdrnv
The maximum number of triangle elements that can be connected to a segment at an attachment point.
maxfepkts
The maximum number of points considered for the near field computation with the FE card when using specified points.
maxfoges
The maximum number of areas that are described by using the Fock theory.
maxgfmsia
The maximum number of entries in the interpolation tables for the Green’s function of a planar substrate.
maxhacards
The maximum number of HA cards (used internally to set up microstrip ports) that may be present in the .fek file.
maxkanr
The maximum number of “internal” edges (also the number of basis functions) per triangle. It may be larger than 3 if more than two plates share an edge.
maxknonr
The maximum number of nodes that may lie against a segment.
maxl4cards
The maximum number of L4 type loads.
maxlab
The maximum number of labels in a model.
maxlecards
The maximum number of LE cards (which specify a load on an edge between triangles).
maxleedges
The maximum number of edges between two surface triangles that can be loaded with a single LE card.
maxlengz
Dimension of the interpolation table used for the planar multilayer Green’s functions. This variable determines the maximum number of sample points in the z direction.
maxmedia
The maximum number of different media used for the treatment of dielectric bodies in the surface equivalence principle. The surrounding free space (medium 0) is not counted (with maxmedia=1 one dielectric body can be treated).
maxnp
The maximum number of columns and rows which a block in the matrix consists of in the Block-Gauss algorithm which solves the matrix equation. Dynamically 3*maxnp*maxnp*16 Bytes are allocated for 3 blocks in the matrix.
maxnv
The maximum number of connection points between wires and surface triangles.
maxndr
The maximum number of triangles.
maxnka
The maximum number of edges between two triangles.
maxnkapo
The maximum number of edges in the physical optics approximation.
maxnkno
The maximum number of nodes between segments.
maxnlayer
The maximum number of layers for the special Green’s function of a planar substrate.
maxnqua
The maximum number of dielectric cuboids.
maxnseg
The maximum number of segments.
maxntetra
The maximum number of tetrahedral volume elements for a FEM solution.
maxnzeile
The maximum number of basis functions in the MoM area.
maxpoka
The maximum number of bordering edges to the PO area.
maxpokl
The maximum number of wedges in the PO area.
maxpolyf
The maximum number of polygonal plates that can be used to represent a body in the UTD region.
maxpolyp
The maximum number of corner points allowed for a polygonal plate.
maxpovs
The maximum number of label to label visibility specifications set by VS cards (a card with a range sets a number of entries equal to the size of the range).
maxsklayer
The maximum number of layers at an SK card.
maxtlcards
The maximum number of TL cards.
maxutdzyl
The maximum number of cylinders in the UTD region.
nmat
The memory size that may be allocated for the matrix of the system of linear equations. For nmat=0, the necessary amount will be allocated dynamically. The allocation is not specified in Bytes, but in terms of the number of type DOUBLE COMPLEX numbers. (These require 16 Bytes each.) For example, 400 MByte is specified by setting nmat = 400*1024*1024/16. The same effect can be achieved by setting the variable maxallocor maxallocm. Therefore it is unusual to assign a value to nmat.
npuf
The maximum number of control cards that may occur in a loop (for example in a frequency sweep).
