Uchanganuzi wa mienendo ya mgusano usio wa mstari¶
Kwa uchanganuzi huu, tumia data katika tutorial/14_dynamic_plate_contact.
Kitu kinachochanganuliwa¶
Kitu kinachochanganuliwa ni athari ya kuanguka kwa upau wa mraba kwenye uso wa sakafu; umbo linaonyeshwa katika Mchoro 4.14.1 na data ya mesh katika Mchoro 4.14.2.

Mchoro 4.14.1 Umbo la sakafu na upau wa mraba
Mchoro 4.14.2 Data ya mesh ya sakafu na upau wa mraba
Maudhui ya uchanganuzi¶
Tunaweka kasi ya awali ya 4427 mm/s kwa upau wa mraba unaochanganuliwa na kufanya uchanganuzi wa mienendo ya mgusano. Data ya udhibiti wa uchanganuzi imeonyeshwa hapa chini.
