Introduction

Thismanualisintendedasanaddendumtotheon-linedocumentationregardingPost-processingingeneralandtheFieldCalculatorinparticular.TheFieldCalculatorcanbeusedforavarietyoftasks,howeveritsprimaryuseistoextendthepost-processingcapabilitieswithinMaxwellbeyondthecalculation/plottingofthemainfieldquantities.TheFieldCalculatormakesitpossibletooperatewithprimaryvectorfields(suchasH,B,J,etc)usingvectoralgebraandcalculusoperationsinawaythatisbothmathematicallycorrectandmeaningfulfromaMaxwell’sequationsperspective.

TheFieldCalculatorcanalsooperatewithgeometryquantitiesforthreebasicpurposes:

plotfieldquantities(orderivedquantities)ontogeometricentities;

performintegration(line,surface,volume)ofquantitiesoverspecifiedgeometricentities;

exportfieldresultsinauserspecifiedboxoratauserspecifiedsetoflocations

(points).

Anotherimportantfeatureofthe(field)calculatoristhatitcanbefullymacrodriven.Alloperationsthatcanbeperformedinthecalculatorhaveacorresponding“image”inoneormorelinesofmacrolanguagecode.Post-processingmacrosarewidelyusedforrepetitivepost-processingoperations,forsupportpurposesandincaseswhereOptimetricsisusedandpost-processingmacrosprovidesomequantityrequiredintheoptimization/parameterizationprocess.
