Comsol Multiphysics 5.3.1.229

All COMSOL software products undergo stability improvements that are introduced as updates.
- Fixed a problem with highlighting of search results in the Documentation window.
- Corrected an issue that made it impossible to copy and paste text from the Help window in the COMSOL Desktop environment.
- Added the Moving Mesh node, available as a subnode to Component > Definitions, to the model tree when selecting Modify model configuration for a study step. The available options are: Solve for and Disable in solvers.
- Improved handling of the Prescribed Normal Mesh Velocity boundary conditions on deforming domains. The change makes domain volume changes consistent with the prescribed normal velocity.
- Increased robustness for Deforming Domain features. The default mesh smoothing method has changed from Laplace to Yeoh. The Yeoh method is more robust at a small additional computational cost.
- Moving Mesh nodes, added under Definitions > Moving Mesh, now include an Override section that contains information about how such nodes override each other. It is also possible to move such nodes and to copy and paste them.
- Added the capability for PDE-based Mathematics interfaces to be active on domains that are part of an Absorbing Layer feature.
- Corrected a problem with Geometry selections so that those that are dependent on a parameter maintain the same dependence when used under Results.
- Fixed a problem with using Function Switch nodes that accessed file resources.
- Corrected user-defined model inputs so that they now show all components instead of only the in-plane components.
- Fixed a problem with search parameters in the Application Libraries window.
- Added support for search parameters based on results in the Application Library window. You can now search using strings such as @dataset, @numerical, @export, and @report.
- Japanese-language versions of the Software License Agreement and the Introduction to COMSOL Multiphysics PDF documents are now made available when installing the software in Japanese.
- Improved the alignment of custom thumbnails in the COMSOL Server Application Library page.
- Corrected an issue with the Wall condition so that Rayleigh roughness can be used in combination with a user-defined absorption coefficient.
- Fixed a problem with the definition of the fluid bulk modulus postprocessing variable in the Poroelastic Waves interface.
- Fixed a problem where the automatic check-in of the CADREADER license file feature was delayed in some environments. The CADREADER license file feature enables the ability to import CAD data files in the CAD-interfacing products.
- Corrected a problem with the shape function order for certain Bubbly Flow variables when used in combination with P2+P2 and P3+P3 elements.
- Corrected a few problems that could occur when using phase-specific turbulence models and the Euler-Euler interface.
- Fixed a problem with the Interior Fan condition for the Reacting Flow multiphysics coupling.
- Fixed a problem with the Interior Fan and Screen conditions for turbulent nonisothermal flow models.
- Corrected the reaction rate constant for surface reactions imported from the CHEMKIN software.
- Corrected a sign error in the potential shift for models using an Ion-Exchange Membrane Boundary node.
- Corrected a problem where the Matrix Histogram plots were not generated for a Cumulative Damage interface.
- Fixed a problem with the stabilization formulation for models where a Translational Motion feature is combined with a user-defined coordinate system.
- Corrected the temperature dependency for general thin layers material.
- Added support for multiple instances of the Medium Properties feature in the Radiative Beam in Absorbing Media physics interface.
- Fixed an issue with mphsave on Windows operating systems that prevented saving a file to an unmapped network drive.
- Fixed a problem with mphplot that prevented older versions of the MATLAB software to work with COMSOL Multiphysics software version 5.3a.
- Improved performance when opening a file that contains selections with a large number of entities in the selection.
- Corrected an error in the Storakers hyperelastic material model.
- Fixed a problem that made it impossible to solve optimization models that have no physics-based study step.
- Corrected some transformations of the Stokes parameters and phase when tracing polarized rays through a graded-index medium.
- Added support for including a Perfectly Matched Layer feature in a model containing a Schrödinger Equation interface with only a Semiconductor Module license.
- Improved the Membrane interface formulation for cases where an additive strain decomposition was selected in a geometrically nonlinear study. A nonlinear strain formulation is now used instead of a previous linear strain formulation.
- Corrected an "Undefined Variable" error in the Thin Film Damping interface.
- Added support for generalized plane strain when combining piezoelectric and linear elastic materials.
- Corrected some problems that would occur when using friction in a Bolt Thread Contact feature.
