Postavke analize¶
Raspakirajte kod FrontISTR-a, prijeđite u direktorij ovog primjera i provjerite jesu li sljedeće datoteke potrebne za analizu
| Naziv datoteke | Vrsta | Uloga |
|---|---|---|
| hecmw_ctrl.dat | Opći upravljački podaci | |
| hinge.cnt | Upravljački podaci analize | |
| hinge.msh | Podaci mreže | |
| hecmw_part_ctrl.dat | Podaci upravljanja particioniranjem mreže | Upravljački podaci koji se koriste kada hecmw_part1 dijeli podatke mreže na domene |
prisutne.
Izlaz:
Provedite analizu naprezanja u kojoj se ograničava pomak na učvršćenim plohama, a na plohu opterećenja primjenjuje koncentrirano opterećenje.
Opći upravljački podaci, upravljački podaci analize i podaci upravljanja particioniranjem mreže prikazani su u nastavku.

Postupak analize¶
Za pokretanje FrontISTR-a s MPI-jem najprije podijelite podatke mreže hinge.msh na četiri domene.

Datoteke *.res.* predstavljaju podatke rezultata i sadrže rezultate analize FrontISTR-a za svaki MPI čvor. Mogu se prikazati pomoću REVOCAP_PrePost-a i sličnih alata.
Datoteke *_vis_* predstavljaju podatke vizualizacije i mogu se prikazati općenamjenskim softverom za vizualizaciju. U ovom primjeru izlaz je u VTK formatu, pa za prikaz upotrijebite ParaView ili sličan softver.
