!ELEMENT_ACTIVATION¶

Elementlarni faollashtirish/nofaollashtirishni aniqlash

Parametrlar¶

MODE      = boshqaruv rejimi (FIXED, AMPLITUDE, DAMAGE) [majburiy]
STATE     = element holati (ON: faol, OFF: nofaol) (MODE=FIXED bo‘lganda majburiy)
AMP       = amplituda nomi (MODE=AMPLITUDE bo‘lganda majburiy)
MEASURE   = baholash kattaligi (STRESS, STRAIN) (MODE=DAMAGE bo‘lganda majburiy)
EPSILON   = soxta qattiqlik koeffitsiyenti (sukut bo‘yicha: 1.0E-6)
GRPID     = boshqaruv guruhi ID si

** 2-qator va undan keyingi qatorlar **

MODE = FIXED, AMPLITUDE bo‘lganda¶

Izohlar¶

• MODE yordamida xatti-harakatni o‘zaro istisno rejimlardan biri sifatida belgilang (MODE=FIXED|AMPLITUDE|DAMAGE).
• MODE=FIXED bo‘lganda STATE=ON/OFF bilan elementlar doimo faol/nofaol ekanini belgilang.
• MODE=AMPLITUDE bo‘lganda amplituda qiymatiga qarab faol/nofaol holatni almashtiring (amp_val > 0.5 bo‘lsa faol, aks holda nofaol).
• MODE=DAMAGE bo‘lganda MEASURE=STRESS|STRAIN bilan ko‘rsatilgan kattalik diapazondan tashqariga chiqqan (LOWER ≤ qiymat ≤ UPPER shartini qanoatlantirmagan) elementlar nofaol qilinadi. Nofaol qilingandan keyin ular qayta faollashtirilmaydi.
• GRPID bilan ko‘rsatilgan boshqaruv guruhi !STEP ichidagi ELEMACT, id orqali yoqiladi.
• Agar !STEP ichida ELEMACT, id ko‘rsatilmasa, tegishli element-faollashtirish sozlamasi qo‘llanmaydi.
