Lists Some func tions in ANSY S Fluen t requir e a “list” of objec ts such as numb ers, strings , Booleans , and so on. A list is a Scheme objec t tha t is simply a sequenc e of objec ts termina ted b y the empt y list ,’() . Lists ar e pr ompt ed f or an elemen t at a time , and the end of the list is signaled b y en tering an empt y list. This t ermina ting list f orms the tail of the pr ompt ed list , and c an either b e empt y or c an c ontain values . For c onvenienc e, the empt y list c an b e en tered as () as w ell as the standar d form ’() . Normally , list pr ompts sa ve the pr evious ar gumen t list as the default. To mo dify the list , overwrite the desir ed elemen ts and t ermina te the pr ocess with an empt y list. For e xample , element(1) [()] 1 element(2) [()] 10 element(3) [()] 100 element(4) [()] Enter creates a list of thr ee numb ers: 1, 10, and 100. Subsequen tly, element(1) [1] Enter element(2) [10] Enter element(3) [100] Enter element(4) [()] 1000 element(5) [()] Enter adds a f ourth elemen t.Then element(1) [1] Enter element(2) [10] Enter element(3) [100] () leaves only 1 and 10 in the list. Subsequen tly en tering element(1) [1] ,,’(11 12 13) creates a fiv e elemen t list: 1, 10, 11, 12, and 13. Finally , a single empt y list r emo ves all elemen ts element(1) [1] () 13Release 2019 R3 - © ANSY S, Inc.

After con- vergenc e, you t ypic ally ma y be in terested in solutions f or new elec tric boundar y conditions , tha t is, either f or a new c ell/stack v oltage or cur rent. In such c ases , simply going t o the Boundar y Conditions task page and changing the v alue of the elec tric potential (uds-0 ) boundar y condition, typic ally allo ws only small changes , most notably f or stacks .
