Welcome to the offical website of the program code Cahmd 1.

This is sample image
User friendly
Cahmd uses a simple text file format to define and run an atomistic simulation. Parameter are defined in natural syntax. The input format allows for simple algebraic expressions, physical units and powerful lists. A graphical interface (GI) allows to handle the input even more easier and give ad-hoc information about the input parameter and examples.
Cahmd has a OpenGL/Vulkan interface that allows visulaization on the fly including certain interactions via mouse and keyboard.
Multiple code approach
Cahmd consist of a multiple-code approach, combinng semi-classical dynamics with a hybrid first-principle electronic structure method. This allows to tackle energy parametrization on an electronic structure basis and even to perform ab-initio dynamics.
Cahmd works naturally with object orentated Fortran and is also interfaced with C++. Thus, adding new features is just linking it to already existign procedures.
