Hello, 

I am trying to run a simulation with irregularities (excitation 108: Stochastic from PSD) generated from a FRA class 3 PSD. My lane is a 2000m tangent with 1980m of irregularities. The problem is that the simulation always stops with an error around 20s (model time is 111s). I cannot understand this error, nor do I know how to fix it. Has anyone had a similar problem? Or do you have any idea what I can do to fix it?
