COMSOL Multiphysics® is used to simulate the transport phenomena in arc welding of Nickel to 304SS. Electric Currents (ec) and Magnetic Fields (mf) are used to solve for the Lorentz force which is one of the volume forces. Laminar Flow (spf) is used to simulate flow field. The Lorentz ...

Flows of electrically conducting liquids in external magnetic fields are present in several applications. In this kind of flow, the inhomogeneous magnetic field creates a breaking force on the conducting fluid. As a result, a stagnant zone is formed in the zone affected by the localized ...

The goal of our work was to calculate a patient-specific brain conductivity map for predicting the extent to which direct stimulation therapy can strategically propagate through pathological white matter. Our laboratory developed isotropic and anisotropic human brain finite element ... En savoir plus
The conductivity of seawater directly correlates with the concentration of dissolved salts. This model demonstrates a new approach to the methodology of inductive conductivity measurement of seawater and other liquids. COMSOL Multiphysics® was used to build a parametrically swept model ...

High temperature superconductors (HTS) such as YBCO coated conductors show great promise for future applications where high magnetic fields are needed. The superconducting state only exists under a critical surface defined in the (J,T,B) space. Quench is the process by which a current ... En savoir plus
NASA is funding the development of a high-fidelity fully superconducting machine sizing tool able to generate optimized designs based on thrust requirements and design constraints. Several mechanical challenges need to be overcome during the design of the torque transfer components. ... En savoir plus
In this paper, we develop and analyze a standard piezoacoustic Tonpilz-transducer model for underwater acoustics in Comsol by addressing the attendant piezoelectric and pressure acoustic multiphysics phenomena. Transducer properties that are studied and characterized are the center ... En savoir plus
We demonstrate the use of COMSOL Multiphysics with MATLAB to model signal generation in wide-bandgap semiconductor radiation detectors. A quasi-hemispherical detector design is compared with a simple, planar detector. Results show that the quasi-hemispherical design can simply and ... En savoir plus
This work describes a way to apply 3D Finite Element Analysis (FEA) to the thermal design of power electronic modules using simplified geometry models of the system components. The method here presented can overcome the problem of solving equation systems with a very high number of ... En savoir plus
Microelectrodes demonstrate that modeling is crucial for understanding the behavior of complex electrochemical systems. The use of the finite element methods in electrochemistry may be of much more general interest for its ability to handle complex geometries. In this context a ... En savoir plus
