New Functionality in Version 4.2

  • Symbols for boundary conditions and loads in the Graphics window.
  • A new study type, Prestressed analysis, Eigenfrequency, available for the Solid Mechanics, Shell, and Plate interfaces
  • A new study type, Prestressed analysis, Frequency domain, available for the Solid Mechanics interface.
  • Built-in computation of beam cross-section properties for a number of common cross sections in the Beam interface.
  • Springs and dampers are available for points, edges, boundaries, and domains for all interfaces in the Structural Mechanics Module.
  • Thin elastic layers are available on interior boundaries and between pairs in assemblies.
  • Added mass can be specified for edges, boundaries, and domains for all interfaces in the Structural Mechanics Module.
  • The force on the rigid connector can be given an arbitrary position.
  • For the rigid connector you can give mass and inertial properties either directly or through declaring a domain as rigid.
  • Improved default solver settings for the Thermal Stress and Joule Heating and Thermal Expansion interfaces.
  • The Fluid-Structure Interaction interface has been updated and enhanced with improved solver settings.
  • Geometric nonlinearity is available also in the Thermal Stress and Joule Heating and Thermal Expansion interfaces.
  • Plasticity can now be added to domains selectively without redefining the underlying elastic data.
  • Plasticity is now supported for orthotropic and anisotropic materials.
  • Damping is available also for hyperelastic and elastoplastic materials.
  • Infinite elements for truncating models covering large domains are available.
  • The contact pair penalty factors have better defaults that are available for all material models.
  • The contact pair can have different offset expressions for the source and destination side boundaries.

Backward Compatibility vs. Version 3.5a

Plane Stress

Version 4 represents the out-of-plane strain as a separate degree of freedom. Plane stress models made with version 3.5a need to be re-solved to correctly display strains and stresses. Displacements are correctly displayed.
