Morphogenesis is a tightly regulated process that has been studied for decades. We are developing data-based and image-basd mechanistic models for a range of developmental processes with a view to integrate the available knowledge and to better understand the underlying regulatory logic. In our previous papers on simulating organogenesis with COMSOL (German et al COMSOL Conf Procedings 2011; Me...

This work presents a different use of COMSOL, not only as a simulation platform for engineering tasks, but also as an integrated component of a computational AI tool framework used to automate designs creation. CNS-Burst is a computational synthesis method used to create solutions to an assigned design task. This search method, iteratively applied, finds design alternatives and represents them ...

Organogenesis is a tightly regulated process that has been studied experimentally for decades. Computational models can help to integrate available knowledge and to better understand the underlying regulatory logic. We are currently studying mechanistic models for the development of limbs, lungs, kidneys, and bone. We have tested a number of alternative methods to solve our spatiotemporal diffe...

In this article nickel interdigital capacitors were fabricated on top of silicon substrates. The capacitance of the interdigital capacitor was optimized by coating the electrodes with a 60 nm layer of HfO2. An analytical solution of the capacitance was compared to electromagnetic simulations using COMSOL and with experimental measurements. Results show that modeling interdigital capacitors usin...

Droplet impact onto a solid surface is modeled and numerically simulated using an ALE formulation of the Navier-Stokes free surface equations. The triple line dynamics aspect is modeled implicitely through the Shikhmurzaev theory. Those equations involve a generalized Navier slip boundary conditions with the variation of the surface tension near the triple line (thus a local Marangoni effect). ...

Proportional solenoids are wellknown and used in a wide range of applications today. However, the theory behind the functional principle of proportional magnetic actuators is not very well represented in literature. This paper discusses methods of influencing the characteristic force-strokecurves of magnetic actuators by means of different pole geometries. The conical design of the stator pole,...

Mastery of finite element theory is necessary to write finite element program, but it is not necessary to use COMSOL Multiphysics package. It is only necessary to understand the physical problem at hand, how to use the finite element program, and how to interpret the results. This paper gives an introduction to modeling in COMSOL Multiphysics, as being employed in the course heat transfer, by d...
