K. Leung [1], A. Imanian [1],
[1] Technical Data Analysis, Inc., Falls Church, VA, USA

Additive manufacturing technology is becoming more popular for the fabrication of metal products as it offers rapid prototyping and large design freedom. However, part quality of components fabricated by current additive manufacturing technology is not comparable to that produced by ... Read More

Modeling Solid-Liquid Settling System as a Two-Phase Flow Problem

L. Gyurik [1], A. Egedy [1], Zs. Ulbert [1],
[1] University of Pannonia, Veszprém, Hungary

Sedimentation is a challenging two-phase problem to model and simulate. Many applications in the industry use sedimentation for separation. For example treatment of wastewater often carried out in settling basins. Different types of the sedimentation process include independent and zone ... Read More

Adaptive Mesh Refinement: Quantitative Computation of a Rising Bubble Using COMSOL Multiphysics®

T. Preney [1], P. Namy [1], J.-D. Wheeler [1], ,
[1] SIMTEC, Grenoble, France

The mesh is a key component in numerical simulations as it represents the spatial discretization of the model geometry. To accurately measure the variation of the unknowns, a relevant mesh should have a high density of degrees of freedom in regions where the norm of the gradient of the ... Read More

Mechanical Damage Models for Concrete

M. Laviña [1], A. Idiart [1],
[1] Amphos 21 Consulting S.L., Barcelona, Spain

Damage models can be used to simulate the quasi-brittle behaviour of cementitious materials, since they can represent cracking in a smeared-way under various loading conditions. COMSOL Multiphysics® developed a functionality to access external material models for structural mechanics in ... Read More
