Users can now configure their Ansys Elastic Licenses settings using the Licensing Config, besides the pre-existing option of using the ANSYS_ELASTIC_CLS environment variable.
DEVICE Suite Enhancements
Starting with the 2022 R1.1 release, Business (standard) and Academic licenses will be sharing the solve license when running concurrent Multiphysics (DEVICE Suite) parametric sweep on the local computer (localhost). You can run sweeps concurrently up to a total of 32 cores on the local machine utilizing 1 solve license.
FDTD solver object now returns performance counters as a simulation result. After running a simulation, users can find useful information such as time to calculate the mesh or to run simulation as a result of the solver (similar to what is currently available in the log file). This new feature will allow users to automatically check for simulation performance against thread counts and optimize their resource settings.
The new option “auto scale pml parameters” in the FDTD boundary condition settings improves the performance of PML boundaries, especially in simulations with very fine mesh or where BFAST is used with steep angles.
The layer builder object now supports custom design for active photonic components. This includes support for doping profile information as well as electrical and thermal material properties in the process file. Designers can now load a compatible process file along with a GDS of their active component to automatically generate the 3D geometry complete with 3D doping profiles in CHARGE. New support for index perturbation type material in the process file allows simulation of optical modulators in FDTD or MODE after running electrical and/or thermal simulations with CHARGE and/or HEAT.
The new integration between FDTD/MODE and Virtuoso Layout Suite can now be utilized from Virtuoso via a brand new Lumerical integration button.
SYSTEM Suite Enhancements
CML Compiler improvements
The mach_zehnder_modulator and the mach_zehnder_modulator_2x2 photonic models now support compact model generation of thermo-optic switches.
The photodetector_simple photonic model now supports compact model generation of harmonic photodetectors.
The photonic Verilog-A model for forward-biased (electrical) phase shifter now supports the modeling of temperature-dependent current-voltage relationship.
New photonic Verilog-A model for parameterized directional couplers.
