On the generation of submarine landslide models for Material Point Method simulations through bathymetric data

Resumo

Submarine landslides are natural phenomena that can cause economic problems and environmental disasters, as the force of the sliding mass can break pipes, interrupting production and destroying whole ecosystems. By simulating these landslides using bathymetric data, one can optimize the design and construction of subsea equipment to minimize its risks. This work aims to create a wizard that, using bathymetric data, guides the engineer through the process of creation of the simulation input for the submarine landslide study. The simulator used was developed in-house and uses the material point method to solve continuum mechanics momentum conservation equations for a vast library of constitutive models. The wizard objective is to streamline numerical parameters by automating and optimizing model choices inherent to the computational method, allowing the engineer to focus on the physical problem rather than the numerical details. Furthermore, it will be possible to configure a vast range of physical parameters, such as the definition of the sliding mass, the constitutive model and its parameters.
