DUAL ENGINE GEMOTRY MODELING™

With the FEMAP Professional Bundle, Dual Engine Geometry ModelingÔ makes it possible to work with either the ACIS Geometry Engine and/or the Parasolid Geometry Engine. FEMAP can create solid models with both engines in the same FEMAP model. Since the underlying engines themselves are not directly compatible, you cannot make the two geometric solids interact, but you can mesh solids from either engine and connect them with FEA entities.

Why both engines?
With the growing acceptance of mid-range solid modeling packages using both ACIS and Parasolids, engineers are often presented with solid models from either of these packages, sometimes from suppliers who might be using a different CAD package, and sometimes from different sources from within the same company.

FEMAP uses the Parasolid Geometry Engine as the underlying geometry evaluation and processing tool when importing, stitching, and working with trimmed and untrimmed B-Spline surfaces. Therefore, even if your preferred mode of solid modeling was ACIS, Parasolid would still be required to import IGES trimmed surfaces, or use the advanced surface modeling capability of FEMAP - Professional.
