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 ... Mehr lesen
Sediment transport in shallow water is of concern in many hydro-ecological problems. Erosion or sedimentation processes are not only relevant in perennial systems as rivers, lakes, reservoirs and coastal regions, but also in ephemeral phenomena like gullies, inundations and floods. ... Mehr lesen
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 ... Mehr lesen
Assessing the severity of the internal corrosion of structures is of paramount importance in the oil & gas industry. Modelling and simulation of this process proved to be key techniques to understand its mechanism and the main factors influencing its severity [1-4]. Considerable ... Mehr lesen
Plasma electrolytic polishing (PeP) is an electrochemical method for surface treatment. In detail PeP is a special case of anodic dissolution [1] that unlike electrochemical polishing requires higher voltage and uses environment friendly aqueous solutions of salts. When the process ... Mehr lesen
The project was ordered by a Swiss watchmaker. The aim was to modelize and optimize the acoustic of a minute repeater on one of the high range item made by the watchmaker. Therefore we based our work on a simplified geometry made by Creo. The mesh model includes the gongs, the bottom ... Mehr lesen
Partial differential equations on unknown domains is a mathematical problem that arises in many applications. Several examples can be easily found in the dynamics of free surfaces in fluid dynamics or in fluid-structure interactions. In many situations, large deformations are encountered ... Mehr lesen
Lyophilization is a food preservation process that allows to inhibit the growth of bacteria and other contaminants by removing water content in the processed food. Conventional vacuum dryers provide heat by thermal conduction to assist the phase change transformation, but if the product ... Mehr lesen
The blast furnace is a counter flow reactor to produce pig iron. The molten pig iron and byproduct slag are accumulated at the hearth of the furnace, from where they are tapped regularly. The blast furnace has to stay continuously in operation for many years to prevent solidification of ... Mehr lesen
Structural safety assessment of cultural heritage masonry structures plays an important role in safeguarding their integrity and conservation. In this regard, masonry modeling is one of the most challenging tasks, since an accurate reproduction of its mechanical behavior is necessary to ... Mehr lesen
