Hello,
It doesn't seem normal to get an integrator error on the first step of history. Your initial integration algorithm may not be a reasonable one, you are probably using an explicit algorithm that does not meet the stability criteria. If the analysis continues all the way to the other algorithm you are referring to, it should be good.
Thank You
