Rotary encoder:
quadrilateral finite element mesh generated from data contained in IGES file.

One of the most complex models successfully processed by QUAD_SURFACE is rotary encoder:
a type of electro-mechanical device that converts
the angular position or motion of a shaft or axle to analog or digital output signals.
Design of rotary encoders involves using a CAD system that produces an IGES file.
Such files commonly contain a significant number of irregularities and errors,
since they are human-created by a draftsman. We consider a typical rotary encoder,
with cable attached, as shown in images below.

This model demonstrates capabilities of our leading mesh generation product
QUAD-SURFACE 4.0. The model data were contained in an IGES file that was successfully
preprocessed and converted into QUAD-SURFACE native text format by our IGES preprocessor/converter.
The model contais, for example, such irregularities as
long-and-narrow domains. The major problem with processing such domains
is step size selection: due to extremely low distances between different curves,
representing the boundary of the domain, step size (and, consequently,
the dimensions of to-be-generated finite elements) must be very small.
Automatic step size calculation is a matter of extreme importance,
and it has been successfully implemented in the converter. The user
can also manually adjust step sizes on any particular boundary curve,
for example with the purpose of minimization of the total number of generated
finite elements in the model.

QUAD-SURFACE 4.0
is our company's
top-of-the-range quadrilateral finite element mesh generator
for planar and curved surfaces in 3D space. QUAD-SURFACE uses its proprietary input data format,
which is perfectly suitable for generation of finite element models.
