LSTC LS-DYNA MPP v13

LS-DYNA, developed by Livermore Software Technology Corporation (LSTC), is a multi-purpose explicit and implicit finite element and multiphysics program used to analyse the nonlinear response of structures.

Its fully automated contact analysis and wide range of material models enable users worldwide to solve complex, real-world problems.

LS-DY­NA is a gen­er­al-pur­pose fi­nite el­e­ment pro­gram ca­pa­ble of sim­u­lat­ing com­plex re­al world prob­lems. It is used by the au­to­mo­bile, aero­space, con­struc­tion, mil­i­tary, man­u­fac­tur­ing, and bio­engi­neer­ing in­dus­tries. LS-DY­NA is op­ti­mized for shared and dis­trib­uted mem­o­ry Unix, Lin­ux, and Win­dows based, plat­forms, and it is ful­ly QA’d by LSTC. The code’s ori­gins lie in high­ly non­lin­ear, tran­sient dy­nam­ic fi­nite el­e­ment analy­sis us­ing ex­plic­it time in­te­gra­tion.

“Non­lin­ear” means at least one (and some­times all) of the fol­low­ing com­pli­ca­tions:

  • Chang­ing bound­ary con­di­tions (such as con­tact be­tween parts that changes over time)
  • Large de­for­ma­tions (for ex­am­ple the crum­pling of sheet met­al parts)
  • Non­lin­ear ma­te­ri­als that do not ex­hib­it ide­al­ly elas­tic be­hav­ior (for ex­am­ple ther­mo­plas­tic poly­mers)

“Tran­sient dy­nam­ic” means an­a­lyz­ing high speed, short du­ra­tion events where in­er­tial forces are im­por­tant. Typ­i­cal us­es in­clude:

  • Au­to­mo­tive crash (de­for­ma­tion of chas­sis, airbag in­fla­tion, seat­belt ten­sion­ing)
  • Ex­plo­sions (un­der­wa­ter Naval mine, shaped charges)
  • Man­u­fac­tur­ing (sheet met­al stamp­ing)

LS-DY­NA’s po­ten­tial ap­pli­ca­tions are nu­mer­ous and can be tai­lored to many fields. In a giv­en sim­u­la­tion, any of LS-DY­NA’s many fea­tures can be com­bined to mod­el a wide range of phys­i­cal events. An ex­am­ple of a sim­u­la­tion, which in­volves a unique com­bi­na­tion of fea­tures, is the NASA JPL Mars Pathfind­er land­ing sim­u­la­tion which sim­u­lat­ed the space probe’s use of airbags to aid in its land­ing. LS-DY­NA is one of the most flex­i­ble fi­nite el­e­ment analy­sis soft­ware pack­ages avail­able.

LS-DY­NA con­sists of a sin­gle ex­e­cutable file and is en­tire­ly com­mand line dri­ven. There­fore all that is re­quired to run LS-DY­NA is a com­mand shell, the ex­e­cutable, an in­put file, and enough free disk space to run the cal­cu­la­tion. All in­put files are in sim­ple ASCII for­mat and thus can be pre­pared us­ing any text ed­i­tor. In­put files can al­so be pre­pared with the in­stant aid of a graph­i­cal pre­proces­sor.

There are many third par­ty soft­ware prod­ucts avail­able for pre­pro­cess­ing LS-DY­NA in­put files. LSTC al­so de­vel­ops its own pre­proces­sor, LS-Pre­Post, which is freely dis­trib­uted and runs with­out a li­cense. Li­censees of LS-DY­NA au­to­mat­i­cal­ly have ac­cess to all of the pro­gram’s ca­pa­bil­i­ties, from sim­ple lin­ear sta­t­ic me­chan­i­cal analy­sis up to ad­vanced ther­mal and flow solv­ing meth­ods. Fur­ther­more, they have full use of LS-OPT, a stand­alone de­sign op­ti­miza­tion and prob­a­bilis­tic analy­sis pack­age with an in­ter­face to LS-DY­NA.
