Courses Introduction to GoldSim This free, self-paced Course is intended to provide you with an introduction to probabilistic, dynamic simulation, specifically focusing on the use of the GoldSim software tool. This Course covers all the key features of GoldSim required for you to start building complex models. Although the Course was primarily designed for those who are new to GoldSim, existing GoldSim users are also likely to find many parts of the Course to be of value. The GoldSim Contaminant Transport Module This Course is currently under development (and is expected to be available by the end of 2021). This free, self-paced Course is intended to provide you with an introduction to the GoldSim Contaminant Transport Module. The GoldSim Contaminant Transport Module is a program extension to GoldSim that allows you to simulate the release, transport and fate of mass (e.g., contaminants) within complex engineered and/or natural environmental systems. This Course assumes that you are already familiar with the basic GoldSim framework (e.g., have taken the Introduction to GoldSim Course).
