  • You should be fa­mil­iar with LS-DY­NA®.


This class overviews how to use the EM solver for Ed­dy cur­rent ap­pli­ca­tions. This course is rec­om­mend­ed for at­ten­dees who have in­dus­tri­al ap­pli­ca­tions that in­volve Ed­dy cur­rents, such as elec­tro­mag­net­ic met­al form­ing, in­duc­tive heat­ing, and rail­guns.

    • Cou­pling with the struc­tur­al and ther­mal solvers
    • How to op­ti­mize the analy­sis and take "short­cuts"
    • The ax­isym­met­ric solver
  • EM con­tact and ero­sion
    • The rail­gun ex­am­ple
