Model Generation
Efficient, effective FEA begins with a thoughtful modeling process.
- 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.
- 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- Overly complex, flawed, incomplete, or outdated CAD data may thwart push-button meshing solutions, and on-the-fly design iteration may be onerous to accomplish with a geometry-reliant automatic mesher.
