Abstract

We introduce AC-SAMMM (The AaChen platform for Structured Automatic Manipulation of Mathematical  Models), a new software infrastructure  for efficient transformation  and evaluation of expressions and their higher-order derivatives. We describe the way this software can be used to perform automatically  the translation  of a model written  in an equation-oriented language like Modelica into a subset of C/C++ and the generation of the model’s higher-order derivative code by algorithmic differentiation  (AD) techniques. The derivatives are generated, using the derivative code compiler (dcc), an AD tool which provides source code transformation  for a restricted but  numerically relevant subset of C/C++. dcc can be applied repeatedly to its own output, to generate derivative codes of arbitrary order.
