Backward Compatibility with Version 5.2 and Earlier
Perfectly Matched Layers physics feature no longer available
The Perfectly Matched Layer physics feature that for version 5.2 and earlier versions was marked deprecated is no longer available. Thus, models using the Perfectly Matched Layer physics feature, must first be rebuilt in a version earlier than 5.2a to use the Perfectly Matched Layer feature from under the Definitions node, before being loaded in 5.2a.
New Default Value for Gaussian Beam Background Field Spot Radius
The Gaussian beam background field is based on the paraxial approximate solution to Helmholtz’ equation. Since this approximation is less accurate for small spot radii, the default value for the spot radius has been changed from one wavelength to ten wavelengths.
Port Phase Parameter Renamed and Relocated
The parameter Port phase, which was previously located in the Port Properties section, is now called Mode phase and is located in the Port Mode Settings section. The API, however, has not changed.
Boundary Mode Study Sequences no Longer Available in the Model Wizard
Previously, when the Laser Heating multiphysics was selected, the Boundary Mode, Frequency-Stationary and Boundary Mode, Frequency-Transient study sequences were available from the Model Wizard. Now, these two study sequences are removed. Instead, a Boundary Mode Analysis step can be added manually to the Frequency-Stationary and Frequency-Transient studies.
