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.
