Node-level performance analysis of the structural mechanics solver b2000++pro Open
Finite element methods build an essential pillar in modern engineering applications. However,
\nsimulating detailed models with numerous degrees of freedom is computationally
\ndemanding and limit the productivity in those applications. T…

Parallel Machine Learning of Partial Differential Equations Open
In this work, we present a parallel scheme for machine learning of partial differential equations. The scheme is based on the decomposition of the training data corresponding to spatial subdomains, where an individual neural network is ass…

Compressible Flow Simulation with Moving Geometries using the Brinkman Penalization in High-Order Discontinuous Galerkin Open
In this work we investigate the Brinkman volume penalization technique in the context of a high-order Discontinous Galerkin method to model moving wall boundaries for compressible fluid flow simulations. High-order approximations are espec…

Utilization of the Brinkman Penalization to Represent Geometries in a High-Order Discontinuous Galerkin Scheme on Octree Meshes Open
We investigate the suitability of the Brinkman penalization method in the context of a high-order discontinuous Galerkin scheme to represent wall boundaries in compressible flow simulations. To evaluate the accuracy of the wall model in th…
