Abstract

We present an overview of our work on particle based simulations of dynamical MEMS problems. We consider applications from both process and device simulation. The first example is the micro powder injection moulding of powder filled polymers, which involves the complex rheology of a largely deforming feedstock with free surfaces. In the second example, the micro casting of metal alloys, large differences in length scales occur. Here we show that it is useful to couple the particle method to a grid-based approach. This technique is used to simulate thermal conduction between the alloy and the mould efficiently. This hybrid approach is also useful when we require coupling to electrostatic fields. This is illustrated in the third example where we show how the simulation of micropart transport by electrowetting can benefit from particle methods. We wrap up with an example from nano device simulation with particle methods where we consider carbon nantotube resonators. We perform a molecular coarse-graining, resulting in a dissipative particle dynamics model. Without considering all the molecular details, this method naturally includes thermal fluctuations, which cannot be ignored on this length scale.
