Altair Twin Activate® Challenge #2: Physical based modelling of a mass-spring-damper system
Modelica is an equation-based language that is especially well-suited for modeling the behavior of physical components. Activate supports several Modelica libraries, allowing users to create physical-based models, often simpler than their signal-based counterparts. Modelica components are acausal, which means that, instead…

How to model a fuse with PSIM
How to Model a Fuse in PSIM Modelling a fuse in PSIM is an extension of modelling a variable resistor. We use can use a controlled current source and Ohm’s Law, V = IR, or V/R = I. In this way we just need to define R = f(x,y,z, etc). For a fuse R will either be a nominal on resistance or an open circuit modelled by a very…
