APM FEM Add-in

APM FEM is an add-in that designs and calculates machine elements, mechanisms, and structures, and performs general purpose strength analysis using FEM (finite element method). APM FEM includes assembly preparation tools for performing calculations, setting boundary conditions, and specifying loads. An integrated generator of finite-element meshes creates both fixed and variable-size meshes. It also includes post-processor. These functions allow it to work with solid parts and assemblies designed in KOMPAS-3D, and to analyse the behaviour of models when various loads are applied, such as statics, fundamental frequencies, stability, and thermal loading.

APM FEM solves the following linear problems:

  • Intensely deformed states (static calculations)
  • Static strengths of assemblies
  • Stability
  • Thermoelasticity
  • Stationary thermal conduction

Results of calculations include the following:

  • Equivalent stresses and their components, and principal stresses
  • Linear, angular, and total displacements
  • Strains in model components
  • Maps and orthographic epures of internal forces
  • Contact forces within an allowed band of contacts
  • Value of safety factors, and the forms of loss of stability
  • Safety factors and numbers of cycles, as determined by fatigue strength
  • Safety factors as determined by flow and strength
  • Temperature fields and thermotension
  • Centres of gravity, weights, sizes, lengths, areas of surface, model moments of inertia, static moments, and the squares of cross-sections
  • Supporting forces in construction legs, and the cumulative responses adduced to the centres of gravity of models
