Shape Optimization

Non-Parametric Shape Optimization

OPTISHAPE-TS is the business software which contains the nonparametric shape optimization technique by "Traction method".

Nonparametric Shape Optimization proposes the most suitable shape by changing surface shape.
By Traction Method, it needs just the boundary condition.
So the user can easily use this software at various design stages like the detailed design stage, the improvement stage of existing parts, etc.

Production Requirements

The various features, such as cost functions for production requirements, shape restrictions, and shape constraints, enable optimization that considers manufacturing requirements.
For example, considerations include die-drawing and thickness limitations for forging and casting processes, specifying designable areas based on interfering components, and incorporating symmetries such as planar and rotational symmetry.

This approach enables the optimization of shapes while adhering to various production constraints.
