Multi-zone
modelling, BEASY Technical Note, 1995. 
This docucment investigates how BEASY
performs with zoning including a spline modeled using
one, two and five zones. The geometry and loading was
supplied by Rolls Royce and the modeling performed by
BEASY. A table is included which shows the effect of
zoning in terms of disk space and CPU usage.

Report
on modelling of strain ring for 70HV.
Geometry from the DXF file "90505sim.dxf"
was used to create a 2D BEASY model. A set of loadings
was selected to simulate application of torque. The
initial model was automatically meshed and solved. Plots
of stress error norm were used to successively refine
the mesh, in two stages. The third model was accepted
as "accurate enough". Note the refinement
procedure and definition of acceptability would in production
be made more sophisticated. Two strings of internal
points were placed along the centre lines of the strain
gauge arrays, to provide graph plots in those areas.
