Model Generation

Efficient, effective FEA begins with a thoughtful modeling process.

How can we help?

Lets Talk

High-precision Analyses

  • Mesh quality (size, angle, patterning, and transition) can have a tremendous influence on stress results and anything derived from them, like durability. Having the appropriate mesh density in all parts of an assembly can also minimize compute time and save costly hours.
  • Important contact interfaces may require carefully matched mesh to ensure initial clearances aren’t disrupted by the discretization of complex, tightly curved surfaces.  Fastener and connection studies, like weld fatigue, may also require meticulous control in order to adhere to solver or company guidelines.

Large, Complex Assemblies

  •  Complex assemblies involving many attached or moving parts can also be difficult for the inexperienced to manage or model realistically, requiring great organizational skills, attention to detail, and understanding of FE connector behavior.
  •  Overly complex, flawed, incomplete, or outdated CAD data may thwart push-button meshing solutions, and on-the-fly design iteration may be onerous to accomplish with a geometry-reliant automatic mesher.

Efficient, effective FEA begins with a thoughtful modeling process. While automatic meshers can often get the job done for stiffness analysis or non-critical parts, it requires preplanning and a human touch to get accurate results in sensitive areas, handle difficult CAD, or grapple with large assemblies.

The CATI Advantage

There are many scenarios in which analysis can benefit from intelligent, careful CATI modeling. Our FE models are appropriately meshed to purpose with maximum performance in mind, and well-organized so any analyst can use them.
