.. _Summary: Summary ------- *µ*\Grid is a part of the project *µ*\Spectre, which provides an open-source platform for efficient FFT-based continuum mesoscale modelling. Its development is funded by the `Swiss National Science Foundation `_ within an Ambizione Project and by the `European Research Council `_ within `Starting Grant 757343 `_. *µ*\Grid is a C++ library for structured grid data and algorithms. It is designed to be used in combination with *µ*\Spectre, but can also be used as a standalone library. The library provides a set of classes for Cartesian structured grid data and differentiation algorithms. The library is designed to be efficient and scalable, and to be used in combination with modern C++ features, such as template metaprogramming and parallelism. *µ*\Grid has language bindings for Python, which expose the grid through `numpy `_ arrays.
