How to perform a Monte Carlo Simulation over a transient study for sensitivity analysis?

Please login with a confirmed email address before reporting spam

Hi, I am working with a model that uses as physiscs the Richards equation in a 2D domain, this is a transient study. I want to perform Monte carlo simulations over the Darcy flux (one of the variables of the Richards equation called dl.U within the software), this variable is a function of the position (x,y coordinates) and time. I want to perform this Monte Carlo simulations for an specific x,y darcy flux but for all times. However, I cannot do it using just the parametric sweep tool, since there are needed a lot of simulations (more than 10^6) and the software crashed and I cannot proceed with the Ishigami function approach that Comsol proposed in the documentation, since it is not possible to define an analitycal function dl.U, since this is a result of numerical solution for the Richards equation. So I would like to know if someone knows how to perform this kind of study in Comsol?

thank you Camila Forero
