Understand the Dynamics of the FitzHugh-Nagumo Model with an App
In 1961, R. Fitzhugh and J. Nagumo proposed a model for emulating the current signal observed in a living organism’s excitable cells. This became known as the FitzHugh–Nagumo model.

Thermal Modeling of Phase-Change Materials with Hysteresis
Hysteresis occurs when the melting temperature of a material is different from the solidification temperature. We demonstrate the thermal modeling of such a material here.

Modeling the Thermal Curing Process
Polymerization of a thermoset resin is one example of thermal curing, a process in which temperature-induced chemical change occurs in a material.
