I simulate heat transfer in solids and liquid model through a water volume (cylinder shape) ,in time dependent study' I get a point graph for 1D plot group in my results, which is temperature versus time, now I want to add a random noise Node on it to see temperature fluctuation on my graph which is under parameters parent, I give a standard deviation and add the function name in heat source however after press compute in study, it come up with an error saying "Failed to evaluate variable Jacobian in Domain 6",
could you please help me to solve this problem?
thanks.
