Application of Loads

FEARCE incorporates a range of features to aid the engineer in applying loads to FE structures and assemblies.  Using the method of identifying regions to be loaded by geometry rather than node ID’s, a user only has to select a named area and choose what type of load is required. FEARCE will automatically distribute pressure across a surface, ensuring that individual nodes are supplied with the correct force components.

FEARCE also contains a number of bearing models that apply suitable pressure profiles across load areas. The user simply identifies the required load area by name, defines what type of bearing is used and supplies the required bearing force vector. FEARCE will then adjust the nodal forces so that the resulting distributed load is correct for the bearing type.

Loads can also be mapped from external models or files. This is useful for interpolating results from one analysis as boundary conditions on a separate model for a second analysis. Examples are mapping thermal results onto a model as temperature loads (including models from CFD conjugate analyses), or mapping displacements from a complete assembly onto a local model. In all cases the meshes of the parent and child models need not to be similar or be in the same co-ordinate space.

Key Features

  • Pre-processing time reduced thruough automation of load application
  • Increased in accuracy as loads are defined explicitly and any conversions (for example pressure into force) are carried out by FEARCE
  • Load regions are defined as named areas rather than relying on individual node ID's-allowing components models to be easily replaced
  • Bearing models allow accurate profiles to be added automatically regardless of mesh distribuion
  • Mapping of loads between models allows a user to quickly set up local models for detailed assessment
