Implicit Analysis in LS-DYNA®



With this sem­i­nar we aim to give you an overview of the pos­si­bil­i­ties and lim­its of im­plic­it sim­u­la­tions us­ing LS-DY­NA. In re­cent years, the sim­u­la­tion pos­si­bil­i­ties in LS-DY­NA us­ing im­plic­it time in­te­gra­tion have been en­hanced ex­ten­sive­ly. Some ar­eas of ap­pli­ca­tion for im­plic­it analy­ses in­clude lin­ear and non-lin­ear sta­t­ic and tran­sient dy­nam­ic com­pu­ta­tions, nat­ur­al fre­quen­cy analy­ses, spring­back and ini­tial­iza­tion of sys­tems with pre­load. Good scal­a­bil­i­ty is ob­served on many CPU cores, which al­lows for the treat­ment of large scale prob­lems with mil­lions of un­known de­grees of free­dom. The course is rec­om­mend­ed for you if you in­tend to use LS-DY­NA to car­ry out im­plic­it sim­u­la­tions. Ex­am­ples will be giv­en dur­ing the sem­i­nar to il­lus­trate the func­tion­al­i­ty of the im­plic­it op­tions.
