In this work the solution of the structural problem obtained by mean of the velocity approach is presented. More in detail the balance and constitutive equations are expressed in Eulerian form, the mesh is not material. The approach is general, is suitable both for material boundary or no-material boundary and for a generic material model. The Hooke's elastic model and the Anand's plasticity ...

A complete set of engineering moduli for two types of unidirectional composites with large fiber/matrix property contrasts was generated using the finite-element approach based on three sets of boundary conditions employed to calculate macroscopic moduli of statistically homogeneous and periodic heterogeneous materials. The boundary condition-dependent differences in the generated moduli ...

Ensuring the quality of underground water and controlling its quantity is of major concern for the population. Therefore, this subject attracts many students from different specialties at different levels of their curriculum. In fact, the pedagogic objectives of the course may be different according to the level or/and interest of the students and COMSOL is used due to its versatility. In this ...

Chaotic systems may lead to instability, extreme sensitivity and performance reduction. Therefore it is unwanted in many cases. Due to these undesirable characteristics of chaos in practical systems, it is important to recognize such a chaotic behavior. The existence of chaos has been discovered in several areas during the last 30 years. However, there is a lack of studies in relation with ...

The U.S. Naval Academy has used COMSOL as a research tool for many years. Academic usage of COMSOL for student use has only begun in the last five years. Student involvement comes in four types, course-wide usage, focused course related work, student projects and semester-long research projects. A summary of how COMSOL has been successfully used at USNA will be given, showing examples of ...

In this work, the numerical simulation of Mexican softwood (Pinus pesudostrobus) drying is presented by solving a physics-based model. The model was developed by considering the heat and mass transport and the representative elementary volume, which involves the solid, liquid and gas phases. We solved a system of partial differential equations by numerical factorization in COMSOL Multiphysics ...

In this work, a MEMS based condenser microphone [1,2] using Polyimide as the diaphragm has been designed. The microphone structure has a backplate placed on top of the diaphragm. The backplate and the diaphragm are made up of polyimide. The two polyimide plates are separated by air gap which is achieved by using Aluminium as a sacrificial layer in between, which is etched away to create the air ...

High Pressure Processing (HPP) is a leading non-thermal food processing technology that is often cited as a major technological innovation in food preservation. Although it is very early to place this emerging technology among the list of breakthroughs in food processing, HPP has started to become a viable commercial alternative for pasteurisation of value added fruits, vegetables, meat, and ...
Extending Engineering Simulations to Scientists: Food Safety and Quality Prediction Using COMSOL Multiphysics® and LiveLink™ for Excel®

We report an implementation of parallel computing on Amazon Web Services™ (AWS) for touch-sensor modeling. COMSOL Multiphysics® was used to simulate an electromagnetic field distribution in a capacitive sensor assembly. Multiple COMSOL jobs were deployed on separate AWS instances and were executed in parallel. The simulation results indicate that implementation of parallel computing for COMSOL ...
