IBM Release 1.93 A.2. tempest Input File DIPOLE2I.PAR.IN, rectangle node, 0 100 index 1.000000

A.2. tempest Input File: DIPOLE2I.PAR.IN

This file is machine-generated.The real one is much larger than this—56 pages’ worth of point_source statements have been snipped out here. The only reason to read this file at all is to check that, e.g. there are no gaps between different layers of material, and this is probably better done using the DXF export utility and DXF file viewer. When doing so, remember that TEMPEST specifies objects and simulation domain limits in exclusive coordinates, whereas it specifies output planes as inclusive. This means that if basicstep is 0.1 µm, a 10-µm cube of vacuum lying at the origin would be specified as

rectangle node 0 100 0 100 0 100 index 1.000000 0.000000

(which looks as though we’re making it 101 blocks wide instead of 100), whereas asking for the quadrature component of Hy in the same region would be specified as

plot hy steady 0.250000 node 0 99 0 99 0 99 dipole2i_hyq

POEMS looks after this for you—the parameters file that you write would specify both as

xlo = 0 xhi = 10*um ylo=0 yhi = 10*um zlo = 0 zhi = 10*um, just as you would measure with calipers.
