The work presented here deals with the simulation of the cavity filling stage of the injection and micro-injection molding process for thermoplastic materials.
COMSOL Multiphysics gives us the means to take into consideration some other aspects usually neglected in commercial 3D softwares...

The simulation of plasma produced by a dipolar source requires a global, self consistent, modeling of its function.
A first optimization of the dipolar source, magnetostatics, microwave propagation and fast electron trajectories (Particles in Cell (PIC) and Monte-Carlo hybrid method)...

The Oldroyd-B family of viscoelastic fluids are notoriously difficult to model numerically. Standard Galerkin finite element methods are prone to numerical oscillations, and solutions break down as fluid elasticity increases. The situation can be remedied to a certain degree however through...

This paper investigates the Electromagnetic and thermal behavior of Synchronous Axial Flux Permanent Magnet Machines.
The Axial Flux machine employed for tests and simulations has a Soft Magnetic Compound stator core. The electromagnetic analysis is used to assess electromechanical...

A 3D finite element model was used to evaluate the time dependent ground deformation and the stress change caused by a pressure source embedded in a viscoelastic medium.
In volcanic areas, the presence of inhomo-geneous materials and high temperatures produce a lower effective viscosity...

The cold crucible is a useful tool for the elaboration of high purity materials by electromagnetic fields. The application areas range from titanium part elaboration, for the aeronautic industry or in medical prosthesis, to silicon purification for the photovoltaic industry.
In this...

With the recent improvement of X-ray Computed Tomography and robust modeling tools, it is now possible to show that pore scale fluid flow modeled by the Navier-Stokes equation can be used to derive macro parameters of Darcy’s Law, such as the hydraulic conductivity.
The model allows...

To modelize infinite photonic crystal fibre (PCF) with 2D-finite-geometry mode solver, it is necessary to use a perfectly matched layer (PML). We have performed a new type of PML design to simulate propagation in PCFs. The results obtained with index-guiding PCFs are in very good agreement with...

Localized heating is poised to become an integral part of microfluidic devices in various life-science applications. This is catalyzed by the scale of economics, the advantageous fluidic behavior at small volumes, and the ever increasing need for rapid and high throughput assays for pharmaceutical...
