Subject: Re: [o-o] [TSSP] Modeling with ANSOFT
Hi Marco, I doubt that Maxwell will be useful in answering specific questions about arc dynamics, unless there's an interesting analysis module available for it that I haven't heard of yet. Typically, the standard Maxwell suite will perform electrostatic, transient, magnetostatic, thermal and eddy current solutions. If you're just interested in solving the electric field, then probably the easiest way to model the coil would be to represent it as a number of stacked hoops with different voltage assignments, rather than as a continuous helix. I did this once, using SolidWorks to make the mech model, then imported it into Maxwell as an ACIS file. BTW, has anyone here played around with QuickHenry? How easy is it to use?
