Description

Some examples about adding user-defined C++ classes to FreeFem++.

This repository was made to show and explain how one can embed some C++ code within FreeFem++ (itself being built on C++). The main idea is to code in C++, then to call functions and object code from FreeFem++.

FreeFem++ can be found at the following adress : http://www.freefem.org

For those using FreeFem++ for scientific work, information is provided on FreeFem++ website for citing the team that created the code.

Introduction

The exemples are located in different folders. Description of the working of the code content is a work in progress.

The examples shown in this tutorial are still very basic.

One should be aware that FreeFem++ already offers many possibilities that bypass the need for classes.

Each class is provided with a basch script .sh to compile the C++ code into a dynamic library .dylib that is read by FreeFem++ to load the class in the main FreeFem++ code (load.edp for isntance).

Adding a class

Describe how to add a class of simple standard types to FreeFem :

• class_d : for a class with an attribute of type double
• class_str : for a class with an attribute of type str

Adding an array of classes

Describe how to add an array of a class called A to FreeFem :

• class_a : defines class a and the array of class a.

Work in progress : use the KN<T> FreeFem object to make the array.
