Hi,

I was wondering if it is possible to vary gravity (g) with time? To start with I’ve used the PushUp example in AMMR 1.3.1. I’ve got a vector the length of the number of time steps, to represent ‘g’. I then tried to reference ‘g’ in AnyBodyStudy “Gravity = {0, g[iStep], 0}”. But I receive ERROR(SCR.EXP10) …“argument will not be ready for evaluation until moment 'EvaluationMoment”.

Is this not only because it ‘iStep’ is not loaded at the point it tries to evaluate the above, but also because Gravity must be a constant? Can you suggest a method to resolve this?

Thanks in advance,

Chris
