THE FOUNDATION OF ENGINEERING CALCULATE REALIZATION BY MEANS OF CAE

Problem definition and dates Handling
The input date variety is depending on technology type, problem definition and their number increased with problem complexity. The simplification of problem solving consists in for instance:
design of model as symmetry model wherever it is possibly,
compensate 3-dimensional simulation to 2 – dimensional (a matter of course so
it is possible )
using quick and easy tool for components modelling
criteria and boundary conditions set such as the level of desired accuracy,
choosing suitable type of analyse (linear static stress, heat transfer etc.)
application of simulation to complex part from components group (GT
principles)
