Arena simulation - how do i model the following model in ARENA (see description) (new to ARENA)?

Hello, I'm fairly new to ARENA and I have the following problem: I have two queues in which, in each queue, a different order type arrives (both having an arrival rate of exponential 10). Order...

Why are the velocities so high in my Boussinesq approximation Fluent simulation?

Hello, I have a mechanism where air rises due to convective flows. In this simulation, nothing is driving the air except this. I understand that the Boussinesq approximation only works for small...

Do you have the equation of curve?

David Jule Mack

Hey Mostafa,

Assuming you want to draw the tangent in 0.23/0 and you do not know the equation of the curve, the simplest solution is the slope computed from the first two data points ((y2-y1)/(x2-x1)),

Greetings, David
