I would like to use a VarEqn to randomly (Gaussian) vary a set of variables using a user-defined seed term in the Monte Carlo Analysis. The reason why I chose a seed to term is so that I can exactly repeat the analysis data for a specific seed. My problem is that the number of variables in the simulation could increase over time and it appears that a change in the number of variables also changes the values of the original variables for a given seed. Is there a way to create a random variable whose random behavior does not depend on what other variables are present in the simulation?

When you setup the first random variable and you use a seed and for illutative purposes lets say we do ten iteration. If you only keep this signle variable it will always keep the same random number for this variable as long as the seed is not changed. If you add a second variable and leave the number of iteration and seed the same the first ten random number will be the same as before but it needs to split them between two variables now, so in fact the first variable you specified end up with different values.
I had this discussion with the developers and we agreed that the behavior could be added. A request for enhancement (or ATM) will be submitted.
