We are happy to announce a significant update to the Rat GUI, now available for download. This version introduces an improved iron solver with improved field calculation capabilities, as we have transitioned to analytically calculating surface integrals. This ensures a more accurate result of the magnetic field near the surface of objects composed of non-linear materials and permanent magnets. Alongside these advancements, we have also addressed important bug fixes to provide a smoother user experience.
For our macOS users, we’re excited to release a beta version of Rat GUI, compatible with both Apple Silicon and other configurations. The user manual has been updated to include a comprehensive installation guide for macOS, ensuring a hassle-free setup. We would like to bring to your attention a known issue in the macOS version, where the Rat GUI might respond differently after taking a screenshot using the "CMD+SHIFT+5" shortcut. This behavior can be reset by pressing "CMD+SHIFT" on the keyboard.
Finally, we have adopted SuperLU for the preconditioner of non-linear matrices.
We're excited to share the newest version of the Rat GUI, now featuring a significant addition: the Non-Linear Solver. This enhancement facilitates the calculation of the magnetic field for non-linear materials, providing a broader range of applications for our users.
Staying true to our philosophy of community collaboration, we've decided to make the Non-Linear Solver's source code open source. This decision reflects our belief in collective growth, transparency, and the power of shared knowledge.
To assist users in understanding the Non-Linear Solver, we're introducing a draft of our manual. Notably, Chapter 6 (HB-Meshes) delves into objects with non-linear properties. In addtion, Chapter 8 (Distmesh Cross-Section) introduces methods to design almost any shape, which can be very usefull when modeling iron yokes for instance. As the manual evolves, we plan to release weekly updates. Keep an eye on our tutorials page for these updates and additional resources, or click on the image of the manual on the right.
We're extending our online presence! Join us on LinkedIn to stay informed about updates, interact with our team, and connect with other Rat users and supporters.
As the Rat GUI grows, it's crucial that our documentation evolves with it. Our updated EULA and Terms now include new third-party licenses and underscore our commitment to user privacy. Any information shared with us for support purposes remains confidential, reflecting our dedication to trust and security.
Your feedback is essential, and we genuinely appreciate our user's continued support and insights. As always, you can always send us an email with any comment or question you may have.
We've made some strides with our iron solver. Jeroen is now able to calculate the field inside iron based on the field from surrounding coils, thanks to this paper from Le-Van et al. This approach eliminates the need to mesh the air due to the utilization of an integral method. Preliminary tests confirm its reliability, showing consistent results for various meshes. These calculations, conducted in three dimensions, are efficiently completed within minutes. Our team is currently focused on incorporating this solver into the Rat GUI, aiming for its inclusion by September.
Given the attention on the iron solver, this Rat GUI update primarily addresses bug fixes. Do check your inbox for our update email, and it might also be worth a peek in your spam folder just in case.
We hope these enhancements improve your experience with the Rat GUI and support your magnetic modeling endeavors.
We're pleased to present the latest release of Rat GUI, version 2.015.0. After taking some time for development, we've incorporated a range of new features. While we can't cover every detail here, a comprehensive list is available on our downloads page.

Introducing Rat GUI's newest updates, focusing on advanced coil geometries for your projects.
Take advantage of the Frenet-Serret equations for dynamic custom CCT paths. This allows for precise no-hardway-bend coil geometries with HTS tapes, freeing you from traditional modeling constraints.
Our updated FreeCAD macro ensures better handling of the Frenet-Serret frame and non-perpendicular tape edges. Plus, exporting non-rectangular conductors to FreeCAD is now simpler, using a loft connection method. More non-rectangular cross-section options are coming soon.
We appreciate your support and look forward to your feedback.
Post our recent Rat GUI update, we've optimized our software, especially around the CCT Wrapper Models.
For clarity in the Canted Cosine Theta Model, we've added descriptive tooltips. We strive to better Rat GUI with every step, and your feedback fuels us.
Rat GUI's recent update introduces a white-themed design option, available in "Settings -> Themes". This change provides an alternative look for users who prefer a lighter interface.
In the material database, we've added the Fleiter-Bristow fit (refer to Appendix A.3 of this work). This is intended to provide an option that can be more precise in certain low field ranges. This new fit is supplemented with data from the Robinson Research Institute, Tohoku University, and Fujikura.
We've also made changes to the Custom CCT design process. Users now have the option to import paths from a CSV file. The addition of a barycentric rational interpolation algorithm aims to help in creating curves for pitch, radius, and harmonics.
Additional adjustments include more bending options for coils and CCTs and the introduction of the Plasma Ring Coil. We've also updated our calculation tools and data handling features to offer more versatility in designs.
We have released an update to the Rat GUI. For users who haven't received the update notice but want to be included in our mailing list, please get in touch. If you're unfamiliar with Rat GUI, a thirty-day trial is available. Learn more here.
The recent update brings several new features and improvements:
The camera functionality now allows an orthographic view. This feature provides better control over the orientation axis of the viewport. We've also added an export function for Rat Models, enabling direct exports to Abacus mesh files. This is particularly helpful for those incorporating their magnet into platforms like Geant4 for particle physics simulations.
Custom CCT design has seen changes too. Users can now import paths from a CSV file. Additionally, the introduction of the barycentric rational interpolation algorithm aids in creating curves for Custom CCT attributes like pitch, radius, and harmonics.
The update also includes bug fixes, thanks to feedback from our users. If you come across any issues or have suggestions, please contact us at email@example.com.
We're pleased to announce the release of Rat Graphical User Interface (Rat GUI). The interface is designed to simplify interactions with Project Rat, making it accessible for both newcomers and experienced users alike.
What is Project Rat? It's a tool for magnet engineers, facilitating the modeling of magnets and calculating their electromagnetostatic properties. The integration of the Multi-Level Fast Multipole Method ensures a balance between accuracy and computational speed.
