List of Non-Native Files and Descriptions

A list of non-native files with descriptions is given.

Filename
Description
.3di
Artwork file containing data to model IC packages and substrates.
.cdb
ANSYS mesh file which can be imported with the IN card.
.chr
FEST3D file containing the generalised S-parameter matrix and may be exported using the DA card.
.cir
SPICE file which describes a circuit and may be included as a non-radiating general network by means of the NW card, CI card and SC card.
.dxf
AutoCAD geometry file which may be imported using the IN card. (Arbitrary surfaces from meshed .dxf files may be imported. Lines and polyline surfaces can also be import and meshed - see IN card.)
.fim
FEST3D file containing the waveguide modes which may be imported using the AW card.
.ffs
CST far field scan file which may be imported by using the RA and AR cards.
.gbr
Gerber file describing printed circuit boards.
.inp
ABAQUS mesh file.
.isd
Data file containing the field distribution calculated by Feko for coupling with CableMod, CRIPTE or PCBMod.
.mfxml
Orbit/Satimo file containing field data which may be imported by the RA and AP cards.
.nas
NASTRAN geometry file that may be imported using the IN card.
.neu
Geometrical data file which is exported by the program Femap.
.nfd
Sigrity file containing field data which may be imported by the RA and AP cards.
.rei
An XML file for coupling of Feko with Altair PollEx. The .rei file containing the radiated emission data of a PCB calculated in PollEx may be imported using the AJ card (PCB source).
.rsd
File for coupling of Feko with CableMod, CRIPTE or PCBMod. It is usually created by CableMod, CRIPTE or PCBMod, but can also be created by Feko if requested with the OS card (field calculation along lines).
.snp
Touchstone format (v1.0) S-parameter file as created by the DA card. The n refers to the number of ports.
.sph
Spherical wave expansion (SWE) as used by the reflector antenna code GRASP from TICRA (may be exported during a Feko solution using the DA card or used to define a spherical mode excitation in a Feko solution as part of an AS card).
.x_b
Binary version of a Parasolid model file.
.x_t
ASCII version of a Parasolid model file.
