A method for the solidification of a free surface liquid phase is presented and solved with COMSOL Multiphysiscs using a fixed grid.

In this case, the Level set method with phase re-injection for mass conservation is used to prescribe the movement of the free surface of the liquid...

Wave propagation in elastic waveguides is a problem of constant interest from the last decades. Several numerical approaches exist. The most intuitive uses time-marching routines that solve the equations of dynamic equilibrium and supply displacements of the structure nodes as time functions. This...

Acoustic waves are used in SONAR systems for the detection and classification of objects which may be swimming in the water column, proud on the seafloor, or buried below the sediment. In some applications, such as low frequency detection and classification of structurally complex objects immersed...

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...
