Abstract
GENERATION OF THE UNSTRUCTURED FE-GRIDS FOR COMPLEX 2D OBJECTS/NESTRUKTŪRINIŲ BE TINKLŲ GENERAVIMAS SUDĖTINGIEMS DVIMAČIAMS OBJEKTAMS
Highlights
During the last decade a lot of research has been devoted to extension of the advancing front technique to the parallel computers [8, 10, 11]
of the main concerns in a finite element analysis is the adequacy of the finite element grid
The accuracy of the finite element method (FEM) depends on the size
Summary
Pastaruoju metu baigtiniq elementq metodu (BEM) sprendfiama daugelis inZinerijos sriciq problemq. Taciau vienas is BEM triikumq yra tas, kad analizes tikslumas labai priklauso nuo BE tinklo kokybes. Nors visi sie metodai vienas nuo kito gerokai skiriasi, taciau visiems jiems bendra yra tai, kad tinklas turi tureti galimyb~ bilti pritaikomas tam tikrai problemai spr~sti. Infinerijoje sie metodai vis labiau populiareja, nes sprendZiant daugeli infineriniq problemq reikia, kad tinklas biitq tankesnis tik tam tikrose biidingose vietose, o kitur pakakttt ir retesnio. PlokS6q ir erdviniq BE tinklq generavimo lygiagreciaisiais procesoriais, taikant plintancio fronto technik1t, srityje yra daug nuveiktt prof. Sio darbo tikslas yra generuoti pradini nestruktiiriniq baigtiniq elementq tinkl1t, kuriame ivertinami inZinerinio objekto ypatumai. Sios informacijos pagrindu generuojamas pradinis nestruktiirinis BE tinklas, kuriame yra ivertinti konkrecios infinerines sistemas ypatumai. Ekspertine sistema leidzia generuoti skirtingus pradinius BE tinklus priklausomai nuo pradines informacijos apie inzinerin~ sistem
