Tahlil mazmuni¶
FrontISTR manba kodini oching, ushbu misol katalogiga o‘ting va tahlil uchun zarur quyidagi fayllar
| Fayl nomi | Turi | Vazifasi |
|---|---|---|
hecmw_ctrl.dat | Umumiy boshqaruv ma’lumotlari | To‘r ma’lumotlari va tahlil boshqaruv ma’lumotlarining kirish-chiqish fayllarini ko‘rsatadi |
hinge.cnt | Tahlil boshqaruv ma’lumotlari | Tahlil turi, ko‘chish chegaraviy shartlari, jamlangan yuklar va boshqalarni ta’riflaydi hamda yechuvchi va vizualizator boshqaruvini belgilaydi |
hinge.msh | To‘r ma’lumotlari | Chekli elementlar to‘rini hamda uning material va kesim ma’lumotlarini ta’riflaydi |
mavjudligini tekshiring.
Bajarish natijasi:
4.1.1-rasmda ko‘rsatilgan cheklangan sirtlarning ko‘chishi cheklanib, yuk sirtiga jamlangan yuk qo‘llanadigan kuchlanish tahlili bajariladi. Umumiy boshqaruv ma’lumotlari va tahlil boshqaruv ma’lumotlari quyida keltirilgan.
Umumiy boshqaruv ma’lumotlari hecmw_ctrl.dat¶
To‘r ma’lumotlari va tahlil boshqaruv ma’lumotlarining kirish-chiqish fayllari ko‘rsatiladi.

FSTR.msg hinge.cnt hinge_vis_psf.0000
FSTR.sta hinge.msh hinge_vis_psf.0000.pvtu
*.res.* fayllari natija ma’lumotlari bo‘lib, ularda FrontISTR tahlil natijalari saqlanadi. Ularni REVOCAP_PrePost va shunga o‘xshash vositalarda ko‘rsatish mumkin.
*_vis_* fayllari vizualizatsiya ma’lumotlari bo‘lib, umumiy maqsadli vizualizatsiya dasturlarida ko‘rsatilishi mumkin. Ushbu misolda ma’lumotlar VTK formatida chiqariladi, shuning uchun ularni ParaView kabi dasturlarda ko‘rsatish mumkin.
REVOCAP_PrePost yordamida yaratilgan von Mises kuchlanish kontur diagrammasi 4.1.3-rasmda ko‘rsatilgan. Shuningdek, tahlil natijalarining sonli ma’lumoti sifatida tahlil natijalari jurnal faylining bir qismi quyida keltirilgan.
