What is MERRILL?

MERRILL is a finite-element micromagnetic modelling package for rock and planetary magnetism, developed at the University of Edinburgh. It simulates the magnetisation structure of mineral grains at physically realistic scales — linking grain-scale physics to measurable magnetic signals. Full description, capabilities, and workflow →

What you can do here

  • Tutorials — step-by-step guides from first installation to advanced multi-grain modelling.
  • FORCINN — run FORC preprocessing and CNN inversion directly in the browser, no local install required.
  • Downloads — pre-compiled MERRILL packages for macOS and Linux, plus the full user manual.
  • Publications — peer-reviewed literature built on MERRILL.

Recommended path for new users

  1. Read About MERRILL to understand what the software models and why.
  2. Work through Tutorial 1 to install MERRILL and run a first model.
  3. Explore FORCINN to run FORC inversion directly from your browser.
  4. Move to Downloads when you are ready to run larger studies locally.
