As a starter project (SW2010), I am trying to make a crude simulation of a Go Kart rear axle flex when using a combination of 3 bearing supports (see pic below).
For that matter I use the "bearing" fixtures and apply a force at the extremities of my axle
Should be quite simple, yet I keep getting the " model is unstable..." error when using "direct sparse" solver or "status code 9 : matrix singular.." when using the "FFEplus"solver
I must be missing something very obvious. Could someone shade a light on this or suggest a relevent reference document/video tutorial for axle/bearing simulationst?
Thanks in advance for your help,
