The researchers who answered the questionnaire and were strongly interested in
using the capabilities of FRISCO came from the following fields:
- Computer Aided Design (CAD), Computer Aided Modelling (CAM) and
Computer Aided Engineering (CAE).
- Mechanical Systems Design.
- Signal Processing and Filter Design.
- Civil Engineering.
- Fluids, Materials and Durability.
- Robotics.
- Simulation.
In general, all these researchers arrived at a nonlinear
problem since linearization (which is, in general, the usual first step)
was either not possible due to the characteristics of the problem,
or did not provide accurate enough results.
The nonlinear problems to be solved appear mainly in two different ways:
either as a nonlinear system of equations, or as an optimization
problem where the objective function is nonlinear or the feasible set is
defined by some set of nonlinear conditions.
