LEDET

LEDET

LEDET (Lumped-Element Dynamic Electro-Thermal) and is a 2D and 3D finite difference tool for simulating electro-magnetic and thermal transients in accelerator magnets.

It includes electro-magnetic coupling between the turns, 3-dimensional thermal diffusion, ohmic loss, inter-filament coupling loss and inter-strand coupling loss, persistent currents.

It allows simulating transients featuring powering cycles and a variety of quench protection methods: self-protection, energy extraction, varistor, quench heater, CLIQ (Coupling-Loss Induced Quench), ESC (Energy Shift with Coupling).

LEDET is developed in Matlab.

Installation

LEDET is distributed as stand-alone executable Executable compiled for Windows (only), which can be run without an installed version of Matlab. For that to work, you will need to install a freeware software called Matlab Compiler Runtime (MCR). Before running LEDET, please follow this link MCR and install the MCR version named "MCR_R2018a_win64_installer".
