SOLIDWORKS Simulation 2021 Geometry Corrections for Curved Surfaces in Contact

SOLIDWORKS Simulation 2021 Geometry Corrections for Curved Surfaces in Contact

SOLIDWORKS Simulation 2021 has improved the calculations for curved surfaces that come into contact by integrating geometry correction factors. These help improve the accuracy of linear static studies involving cylindrical, spherical and conical contacting surfaces. Take the two cylindrical rings below. After creating a separate configuration with a quarter model of the assembly, the two…

SOLIDWORKS Mass Overrides with Simulation

SOLIDWORKS Mass Override

In some situations, the mass of a component may not match the real world value.  This would be caused by either an improper mass density of the material assigned, or the volumetric geometry is not identical to the physical component.  The most common source is from imported geometry that is missing components or detail. Within…

Heat Flux Singularities in SOLIDWORKS Simulation

Stress singularities are an inherent part of all FEA analyses and they are inevitable in the case of sharp re-entrant corners and edges as well as loads and fixtures that are applied to entities with zero surface area (such as edges and vertices). In such locations, due to mathematical errors, the value of stress increase…
