January 15, 2019, 00:03	Vehicle Overtaking Simulation	#1
mazig New Member Join Date: Nov 2018 Posts: 3 Rep Power: 8	Hi, I'm trying to simulate vehicle overtaking situation in a same domain as a steady-state. The overtaking car's velocity is 160km/h, and the overtaken car's velocity is 140km/h. So I put the overtaking car's relative velocity 20km/h to inlet direction, and inlet velocity 140km/h. I don't know whether the error is negligible. Also, is it ok to simulate that way?
