Contact analysis (sehemu ya 2)¶
Kwa uchanganuzi huu, tumia data katika tutorial/10_contact_2tubes.
Kitu kinachochanganuliwa¶
Uchanganuzi huu ni tatizo la kuingiza silinda; umbo la kitu kinachochanganuliwa linaonyeshwa katika Mchoro 4.10.1 na data ya mesh katika Mchoro 4.10.2.

Mchoro 4.10.2 Data ya mesh ya kitu kinachochanganuliwa
Maudhui ya uchanganuzi¶
Tunafanya contact analysis kwa Lagrange multiplier method, tukitoa prescribed displacement katika mwelekeo wa kuingiza kwenye prescribed surface iliyoonyeshwa katika Mchoro 4.10.1. Data ya udhibiti wa uchanganuzi imeonyeshwa hapa chini.

Utaratibu wa uchanganuzi¶
Tekeleza amri ya FrontISTR fistr1.
(Huendeshwa kwa thread 4)
Matokeo ya uchanganuzi¶
Kwa matokeo ya substep ya 4, deformation plot yenye contour ya Mises stress imeundwa kwa REVOCAP_PrePost na kuonyeshwa katika Mchoro 4.10.3. Pia, sehemu ya faili ya log ya matokeo imeonyeshwa hapa chini kama data ya nambari ya uchanganuzi.
