- Made various usability improvements.
Acoustics Module
- Corrected the global postprocessing variables generated by the Port condition in 2D axisymmetric models.
- Fixed an issue when only one frequency was used in a study together with the Port Sweep functionality.
CFD Module
- Corrected the density and viscosity used for the Inlet boundary condition in the Darcy's Law interface when used with the Multiphase Flow in Porous Media multiphysics coupling node.
- Corrected the implementation for the use of multiple Mass Source nodes in the Phase Transport interface.
- Made various stability improvements.
Chemical Reaction Engineering Module
- Corrected the heat capacity ratio (Cp/Cv) function from the Thermodynamics interface.
Composite Materials Module
- Fixed a problem where, in the Layered Shell interface, spurious stresses could appear in elements with large variations in normal orientation. This issue, which could occur for imported meshes or together with virtual geometry operations, is now fixed.
ECAD Import Module
- Improved the implementation so that the vertical faces are now included in boundary net selections for drill layers in ODB++ files.
Heat Transfer Module
- Fixed the isobaric compressibility coefficient definition when user-defined density is used.1
- Fixed moving mesh support in the shell features.1
- Enabled Surface-to-Surface Radiation multiphysics coupling for the Slip Flow and High Mach Number Flow interfaces.1
- Corrected the expression for Zmean (mean figure of merit) in the Thermoelectric Effect multiphysics coupling.1
- Fixed the out-of-plane thickness contribution to heat flux interface features in 2D geometries.1
- Corrected diffusive heat flux postprocessing variables definition when employing the Heat Transfer with Radiative Beam in Absorbing Media multiphysics coupling.
- Corrected the ambient temperature definition in the Ambient Thermal Properties node when the Temperature list is set to either User-defined coefficient for deviation or User-defined correction.
- Corrected coefficients of a few Legendre polynomials of order higher than 4.
- Fixed out-of-plane thickness to unity and disabled out-of-plane features when a multiphysics coupling involving a radiation interface is active.
- Fixed out-of-plane thickness contribution for turbulent nonisothermal flow with wall functions or automatic wall treatment.
- Fixed the Opaque Surface feature for the Radiative Beam in Absorbing Media interface.
- Fixed density definition in the Phase Change Material node when it is used under the Solid feature with a moving mesh.
- Removed redundant selection filter in the postprocessing dataset of a layered material in order to obtain more concise models.
- Defined overriding between the Irreversible Transformation and Phase Change Material subfeatures.
- Fixed an issue with the mass flow rate definition in the Interior Fan feature.
- Fixed the definition of energy balance postprocessing variables in cases with a multiphysics coupling defining heat sources on boundaries.
- Fixed the thermal conductivity definition in the Phase Change Material node when it is used under the Solid feature with a moving mesh.
- Fixed a migration issue for models containing Heat Transfer with Radiation in Participating Media interfaces built in version 5.3a and earlier.
- Updated the thermal conductivity definition when different material properties are specified for the damaged tissue in the Thermal Damage subfeature.
- Canceled contribution of work done by pressure changes for incompressible flow with Boussinesq approximation for the Nonisothermal Flow interface.
- Removed the possibility to define an out-of-plane thickness in heat transfer interfaces in 1D, 2D, and 2D axisymmetric geometries when heat transfer is coupled with a radiation interface.
- Added display of the radiation direction in the Prescribed Radiosity feature.
LiveLink for SOLIDWORKS
- Added functionality so that the LiveLink interface and the embedded one-window simulation environment now support SOLIDWORKS 2019.
Nonlinear Structural Materials Module
- Corrected an error in the Souza-Auricchio model for shape memory alloys.
- Corrected a problem when a user-defined creep law was created using a Potential in the Creep node. In previous versions, a factor of two was applied to the off-diagonal terms in the potential expression in order to account for the symmetry in the stress tensor. This factor was based on the assumption that the potential expression was written in terms of only the upper-diagonal parts of the stress tensor. With this update, the potential is assumed to be written on a standard form, so that the shear strain rates are directly computed as the derivative of the potential with respect to corresponding stress tensor element.
Particle Tracing Module
- Fixed a problem so that the Heat Source, Convective Heat Losses, and Radiative Heat Losses features for the Particle Tracing for Fluid Flow interface now respect domain selections.
- Improved handling of diffuse scattering or emission of particles or rays from interior boundaries.
- Corrected the coefficient in the Saffman lift force to account for a corrigendum to the original Saffman paper.
- Added auxiliary dependent variables on particles to the Add/Replace Expression menu during results processing.
Pipe Flow Module
- Made improvements so that Pipe Connection features in old models that use the Nonisothermal Pipe Flow interface will import as is, with a warning that the feature is obsolete and will be removed in future versions.
Plasma Module
- Changed the functionality so that the Boltzmann Equation, Two-Term Approximation interface is now only available in 0D components. The old version, which was available in 1D, is now retired. Existing models using the 1D version of the interface can still be opened and modified.
Ray Optics Module
- Implemented additional safeguard against division by zero errors when using the Ray Termination feature.
- Improved the functionality to set automatically the frequency model input for refractive indices that depend on ray frequency or wavelength. If you had previously set the model input manually, for example to comp1.gop.f0, then, after updating, go to Common Model Inputs, right-click Frequency (Hz) -minput.freq and choose Reset to Default.
Semiconductor Module
- Corrected the equation display for Poisson's equation in the Semiconductor interface.
Structural Mechanics Module
- Fixed an error that could occur when adding Adhesion in a Solid Mechanics interface that already contains a Plasticity node.
- Fixed an error that could occur when using Compact History in a model containing a Solid-Beam Connection multiphysics coupling.
- Improved performance for postprocessing with Shell datasets.
- Corrected an error occurring during the generation of default solver sequences for multiphysics models that contain a Damage node in the Solid Mechanics interface.
- Included losses from the Thin-Film Damping feature when computing power dissipation and quality factor in the Solid Mechanics interface.
- Made stability improvements.
Subsurface Flow Module
- Corrected the definition of the Permeability and Kozeny-Carman formulation for Richards' equation to use the relative permeability for calculating the transmissibility.
- Corrected velocity contribution due to gravity with specified acceleration for the Fracture Flow feature.
