Parameters defined by equations

As a new feature, parameters can now be defined as expressions of other parameters.

Basic arithmetic operations, addition, subtraction, multiplication and division, can be applied between two parameters or between a parameter and a numeric value.

Parameter equations

This makes it possible to reduce complex geometries with many parameters to a small set of controlling parameters, for example a single length and a radius, simplifying template definition and use.

Radius constraint

FEM-Design 25 introduces a new Radius constraint as an additional geometric parameter for parameterised structures, solids and regions.

Radius constraint

The Radius constraint can be assigned to curved regions and structural elements, either individually or to multiple selected objects, as a parameterised or fixed radius.

Radius assignment

Radius parameters control the curvature of arcs defined between fixed, locked nodes.
