Topology Optimization

LS-TaSC™ is a Topol­o­gy and Shape Com­pu­ta­tion tool. De­vel­oped for en­gi­neer­ing an­a­lysts who need to op­ti­mize struc­tures, LS-TaSC works with both the im­plic­it and ex­plic­it solvers of LS-DY­NA. LS-TaSC han­dles topol­o­gy op­ti­miza­tion of large non-lin­ear prob­lems, in­volv­ing dy­nam­ic loads and con­tact con­di­tions.
