CAD Data Reuse for CAE

CADfix offers to CAE analysts the ability to automatically and interactively repair and transform CAD geometries prior to analysis. CADfix ensures that solid or surface models are robustly translated effectively into target systems. CADfix offers a full range of import and export functionality for pre-processing CAD data from native and neutral formats.Master Model Driven FEA, CFD, EM Solutions With ever shortening product design cycles, the emphasis on simulation tools to provide timely results to drive the design is greater than ever. This pressure dictates FEA, CFD and EM analysis being driven off the master model CAD data. CAD provides the geometry but a great deal of analysis time is still spent working with the geometry to prepare it for analysis. CADfix for Geometric Exchange is uniquely positioned in the CAD to CAE data flow with its ability to read and write multiple geometric formats, repair and heal poor quality geometry and de-feature and simplify complex geometric definition. In the end, CAE analysts are starting with much more robust geometric definitions for their analytical needs

Geometric reasoning

Geometric Reasoning is accomplished based on the medial object of a solid which is a skeletal representation providing a comprehensive source of information for a variety of applications. Many engineering scenarios require more extensive geometric information than can currently be provided by typical CAD or Product Data Interoperability software products and this is the goal of Geometric Reasoning technology.

Merge and Join geometry

Optimize CAD data for reuse in simulation is the biggest challenge for CAE analysts. CADfix reduce the CAD to CAE process by automating this simplification. An efficiency way to simplify a model is by merging neighbor's faces, edges or solids together

Defeaturing CAD model with CADfix

Preparing CAD models for successful mesh generation continues to be a crucial part of the design to analysis process. A common problem in CAD models is features that are very small compared to the desired mesh size. Small features exist for a variety of reasons and can require an excessive amount of elements or inhibit mesh generation all together.
