The Howdy Glossary

ASCEND is an open-source modeling environment created by Dr. John Pye as part of his Ph.D. studies at the Australian National University in the late 1990s. It is designed for solving equation-based problems, particularly within chemical processes and engineering optimization domains. The software functions as a programming language tailored for mathematical modeling, with syntax resembling other languages such as Modelica, and specializes in simulations to find solutions for specific variables or parameters within a model using equation-solving techniques.

ASCEND stands out due to its specialized focus on chemical process modeling and engineering optimization, offering unique tools tailored for these fields. Its open-source nature provides flexibility and accessibility, allowing users to adapt and customize the software for specific needs while fostering a collaborative development environment. This specialization makes it particularly valuable for professionals, researchers, and students involved in process systems engineering who require efficient solutions to complex problems.

The main competitors of ASCEND include MATLAB/Simulink, Dymola (Modelica-based), Maple, and COMSOL Multiphysics—each providing robust capabilities in mathematical modeling, simulations, and optimization across various fields. However, ASCEND differentiates itself through its dedicated focus on chemical processes and engineering optimization along with its open-source framework that supports adaptation and innovation in these domains. Its alignment with mathematical modeling languages like Modelica further enhances its position by accommodating diverse requirements efficiently within the realms of chemical engineering applications.
