Some im­por­tant ap­pli­ca­tions of the EM solver in­clude mag­net­ic met­al form­ing or weld­ing, in­duced heat­ing and any kind of prob­lem in­volv­ing mov­ing con­duc­tors or work pieces. The videos be­low are ex­tract­ed from some of the stud­ies con­duct­ed us­ing the EM solver.

De­scrip­tion: This study con­duct­ed in col­lab­o­ra­tion with M. Wor­swick and J. Im­bert from the Uni­ver­si­ty of Wa­ter­loo, On­tario Cana­da fea­tures a met­al sheet form­ing on a con­i­cal die (on­ly 1/­2 of the die and the work piece are rep­re­sent­ed). The main ob­jec­tive of this study was to pre­dict the fi­nal shape of the met­al sheet.

De­scrip­tion: This study con­duct­ed in col­lab­o­ra­tion with Ibai Ula­cia from the Uni­ver­si­ty of Mon­drag­on, Guipúz­coa, Basque coun­try, fea­tures a nu­mer­i­cal sim­u­la­tion of bend­ing ex­per­i­ments with a met­al plate Work­piece be­ing forced up­on the rec­tan­gu­lar shaped Die by the Lorentz forces gen­er­at­ed by the Coil.

De­scrip­tion: In col­lab­o­ra­tion with the Fraun­hofer In­sti­tute for the sim­u­la­tion mod­el and Poynt­ing for the Coil+Shaper de­sign, this sim­u­la­tion fea­tures the form­ing of a tube shaft joint (Au­to­mo­tive pow­er train com­po­nent)

De­scrip­tion: In col­lab­o­ra­tion with Dmit­ry Chernikov of the Sama­ra State aero­space Uni­ver­si­ty, Rus­sia, and the re­search lab­o­ra­to­ry "Pro­gres­sive tech­no­log­i­cal process­es of plas­tic de­for­ma­tion", this sim­u­la­tion shows the EM form­ing of an Al tube against a con­i­cal die. The main ob­jec­tive of this analy­sis was to com­pare the sim­u­la­tion re­sults of the dis­place­ment of the out­er edge with the ex­per­i­men­tal re­sults.

De­scrip­tion: Ex­pan­sion an de­for­ma­tion of an Alu­minum cylin­der by a 10 turn coil with a ris­ing cur­rent of 75 kA in 30 mil­lisec­onds. Test case re­alised in col­lab­o­ra­tion with Glenn Daehn, De­part­ment of Ma­te­ri­als Sci­ence and En­gi­neer­ing, Ohio State Uni­ver­si­ty.

De­scrip­tion: This test case con­duct­ed in col­lab­o­ra­tion with the Uni­ver­si­ty of Wa­ter­loo, fea­tures the weld­ing of two met­al pieces against one an­oth­er.

De­scrip­tion: In col­lab­o­ra­tion with Miro Duhovic from the In­sti­tut für Ver­bundw­erk­stoffe, Kaiser­slautern, Ger­many, this test case fea­tures a  pan­cake” type spi­ral in­duc­tion coil mov­ing over a met­al or com­pos­ite plate. The main ob­jec­tive of this test case is to bet­ter un­der­stand the ther­mo­form­ing ca­pa­bil­i­ties of dif­fer­ent ma­te­ri­als.

De­scrip­tion: In­duc­tive heat­ing test case where a plaque mov­ing at con­stant ve­loc­i­ty is be­ing heat­ed by a set of coil.


De­scrip­tion: The TEAM 28 prob­lem presents an elec­tro­dy­nam­ic lev­i­ta­tion de­vice which con­sists of a con­duct­ing plate over two ex­cit­ing coils. The aim is to de­ter­mine the dy­nam­ic char­ac­ter­is­tics of the lev­i­tat­ing plate (af­ter some damped os­cil­la­tions, the plate at­tains a sta­tion­ary lev­i­ta­tion height). A cou­pled so­lu­tion of the elec­tro­mag­net­ic and the me­chan­i­cal prob­lem is hence nec­es­sary.

De­scrip­tion: A rail­gun is an elec­tri­cal gun that ac­cel­er­ates a con­duc­tive pro­jec­tile along a pair of met­al rails. The pro­jec­tile is in con­tact with the two rails and a cur­rent pass­es through the pro­jec­tile. This cur­rent in­ter­acts with the strong mag­net­ic fields gen­er­at­ed by the rails thus ac­cel­er­at­ing the pro­jec­tile. This sim­u­la­tion fea­tures the EM slid­ing con­tact fea­ture that al­lows two con­duct­ing parts to slide one against the oth­er while some cur­rent is flow­ing through them.

De­scrip­tion: This ex­am­ples fea­tures a re­sis­tive heat­ing ex­am­ple with a con­duct­ing wheel rolling on a con­duc­tive plaque us­ing the EM con­tact fea­ture. This al­lows the cur­rent to flow from elec­trodes on the shaft of the wheel to elec­trodes on the plane. This case is cou­pled with the im­plic­it me­chan­i­cal and ther­mal solvers of LS-DY­NA and the tem­per­a­ture fringes are shown here.
