Introduction to ICFD


  • You should be fa­mil­iar with LS-DY­NA®.
  • CFD knowl­edge is ap­pre­ci­at­ed but not re­quired.


This class pro­vides an in­tro­duc­tion to the ICFD solver in LS-DY­NA. The ICFD solver can be run alone for pure CFD ap­pli­ca­tions (the study of drag/­lift around bluff bod­ies and ve­hi­cles for ex­am­ple) or be cou­pled to the ther­mal and struc­tur­al me­chan­i­cal prob­lems for lin­ear and non-lin­ear com­plex FSI and con­ju­gate heat trans­fer ap­pli­ca­tions. It al­so makes use of an au­to­mat­ic mesh gen­er­a­tor for the flu­id vol­ume, thus great­ly re­duc­ing the cost of set­ting up the mod­el. Key con­cepts as well as the phi­los­o­phy be­hind the solver will be dis­cussed in the first part of this class be­fore mov­ing to prac­tice ex­am­ples and key­words in the sec­ond part.
