Making use of the GSSE and using expertise acquired from research in
the field of TCAD, it was possible to develop simulations for problems
from other disciplines of research.
For example, the simulation of a relaxation problem of electric charges
can be applied to problems from the field of biology, such as to describe
the electric fields generated by certain species
of fish. The shape of the simulated fish is shown in the accompanying
figure. The area generating the electric field is shown in red. In
order to provide an easily accessible yet powerful interface, which
can also be employed in education, a web interface to the simulation
has been created. The major simulation parameters can thereby easily
be adjusted, making the simulation more accessible to domain experts
who have no previous experience with simulations. The
arrangement of the simulation domain is shown in the lower part of the
figure. It includes the fish along with an underwater obstacle.
The web application is highly modular and makes extensive use of
standard components. The modular nature provides an excellent
opportunity to load balance several incoming requests to different
calculation hosts. In addition to the ability to delegate the actual
simulation transparently to various hosts, a caching mechanism has also
been included to conserve computational resources. This keeps the load
of the web server to a minimum and thereby ensures good responsiveness
of the interface to user requests.
The results of the simulation are post-processed, visualized again
using modules, and subsequently presented to the user via the web
interface.
