WebbA probabilistic method or model is based on the theory of probability or the fact that randomness plays a role in predicting future events. The opposite is deterministic , which is the opposite of random — it tells us something can be predicted exactly, without the added complication of randomness. What is a Probabilistic Model?

WebbThe fracture plane was discretized into a square mesh to which variable apertures were assigned. The spatially varying apertures of each single fracture were generated using geostatistical methods, based on a given aperture probability density distribution and a specified spatial correlation length. WebbAn iterative process, adjusting the probability of each specimen from the test and model, allows to adjust the Weibull distributions values for the probability of failure of the fracture stress. To apply this procedure, it has been required to carry out a test campaign with enough data to update the finite element model.
