SimWorks releases SimWorks Finite Difference Solutions version 3.1.0

Dear users:
Thank you all for your attention and support to the SimWorks software. To further optimize the user experience and enhance the simulation quality, this software has been updated to version 3.1.0.The key update contents this time are:

Adds the EME Eigenmode Expansion Solver #

The Eigenmode Expansion (EME) solver divides a long waveguide structure into multiple cells along the propagation direction, solves for the eigenmodes of the cross-section in each cell, and then computes the coupling of these modes between adjacent cells to obtain the complete optical characteristics of the entire device.

The EME solver is particularly suitable for analyzing and designing photonic devices with lengths much larger than the wavelength and with slowly varying or periodic refractive index profiles, such as multimode interference couplers (MMIs), fiber Bragg gratings, and adiabatic tapered waveguides. Compared to direct 3D FDTD simulations, the EME solver achieves significantly faster computation speeds while maintaining accuracy, and allows rapid parameter sweeps of key parameters such as device length and wavelength after a single mode calculation, greatly enhancing the design efficiency of photonic integrated circuits.

Slurm Cluster Resources Now Support File Transfer via Shared Folders and Local Slurm Job Submission #

This update brings two major enhancements to SimWorks' Slurm cluster resource management: support for file transfer via shared folders, and the ability to submit Slurm jobs directly from a local machine (Linux only).

• Support for file transfer via shared folders
  This feature allows users to map their local working directory to a shared directory on the Slurm cluster. With just one-time path mapping configuration, the system automatically translates local paths to cluster-recognized paths, enabling direct read and write access to project files and result data without the need for traditional SSH+SCP uploads and downloads. This significantly improves file transfer speed and simplifies workflows, especially for handling large datasets.

• Local Slurm job submission (Linux only)
  Now, users on local Linux hosts with Slurm client components installed can choose the local mode to submit Slurm jobs. In this mode, Slurm commands such as sbatch are executed directly on the local machine to submit computational tasks, eliminating the need to SSH into a remote management node. This "local submission" mode reduces network hops, making job submission more convenient and efficient, and lowers the risk of job submission failures due to network instability.

The local job submission feature is currently supported only on Linux. Users need to configure the job submission method (Local) and file transfer method (Shared directory) in the SimWorks cluster configuration interface, and correctly specify the local-to-remote path mapping.

Adds the rectilinear grid dataset type rectilineardataset #

Adds a new rectilinear grid dataset type rectilineardataset, providing more flexibility for data storage and processing.
