Intact.Simulation is the most flexible mechanical simulation solution in the history of mechanical design. Unlike traditional finite element analysis, which requires manual data preparation and error-prone meshing, Intact.Simulation’s Immersed Method of Moments completely automates processing of diverse and disparate representations at arbitrary resolution, resulting in a fault-tolerant finite element model suitable for conventional solvers. Intact.Simulation improves product quality and process via continuous analytical feedback across all geometry and material models, from concept sketching though detailed design, prototyping, production, and maintenance.
🔍 What is the Immersed Method of Moments™ ?
All material is made of discrete cellular structures, called “elements”. While traditional FEM discretizes geometry, the Immersed Method of Moments (IMM), discretizes space into intelligent cells, creating the appropriate elements for the underlying geometry and material in each cell. In particular, IMM modifies the quadrature rules of standard FE elements, rather than attempting to approximate the geometry itself. IMM decouples test specimens from their analysis and boundary conditions, enabling the same setup to generate data over broad product variations and lifecycle representations.
🧐 How does IMM build on FEA?
For over half a century, the finite element method has dominated structural engineering analysis. However, traditionally FE methods don’t scale well as the complexity of geometry increases, because traditional FEA requires high-quality, body-fitted meshes which may be challenging or impossible to generate on complex geometry.
Intact.Simulation performs equally well on explicit geometry such as meshes and curves and implicit geometry such as voxels and signed distance fields. Intact enables both fast conceptual simulation using coarse linear methods as well as high-fidelity analysis using quadratic elements on a fine grid. In particular, Intact.Simulation can approximate performance of periodic geometry such as lattices at any resolution, from fine fully resolved details to coarse resolutions with effectively homogenized behavior.
Intact.Simulation’s boundary conditions are specified geometrically instead of topologically, which makes it easy to swap out different geometry models in the same test harness, validating performance throughout a product or design’s lifecycle.
