ABSTRACT:
A method for defining at least one parameter for a finite elements analysis (FEA) calculation in a computer-assisted drafting (CAD) program comprises the steps of determining a body for which said parameter is to be defined, said body being a entity processed by said CAD program; and using at least one graphical function of said CAD program to define a region within a face of said body, said region being used to define a load/support condition for said FEA calculation. A computer program product and an apparatus comprise corresponding features. The present invention provides an improved way of defining parameters like load or support conditions for an FEA calculation in a CAD program.
