  • Model generation for cardiac simulations
  • Specialized software development for cardiac simulation pipelines

CARPentry-Pro: The simulation engine

CARPentry-Pro is a commercial implementation of the Multiscale-Multiphysics cardiac simulation software CARPentry (since 2010) and its predecessor CARP, developed between the partners Medical University of Graz and University of Bordeaux. It models cardiac electrophysiology, mechanics and hemodynamics at cellular, tissue and organ scales with unmatched fidelity and performance. CARPentry-Pro and its academic predecessors have been used in > 120 peer-reviewed journal publications. It is used by leading academic labs in Europe and the US, with a base of >100 users worldwide

CARPutils: The experiment definition framework

The increasing complexity of cardiac in silico experiments has prompted the development of a workflow that simplifies the definition and execution of such simulations. CARPutils is designed to encapsulate the technical complexity of in silico experiments at a more abstract level. Once built, limited technical expertise is required to carry out simulations, thus relieving users from undergoing months/years of training, and spending more time on actual research. Furthermore, CARPutils enables the easy sharing of experiments for collaborative research, for re-use of previous/published experiments, or simply, for the sake of remote debugging.

Meshtool: Automated mesh generation and manipulation

Advanced cardiac modeling studies rely on the ability to generate and functionalize personalized in silico models from tomographic multi-label image stacks. Typical modeling workflows involve a multitude of interactive mesh manipulation steps, rendering model generation expensive. Meshtool is software specifically designed for automating all complex mesh manipulation tasks emerging in such workflows by implementing algorithms for tasks describable as operations on label fields and/or geometric features.

CARPentry Studio: Interactive high-performance pre- and post-processing

CARPentry Studio is a pre- and post-processing graphical tool, tailored to the CARPentry simulation workflows. It's feature-set includes

  • surface and volume extraction
  • region re-tagging
  • fiber and reference frame generation
  • mesh transformation, deformation and re-meshing
  • Purkinje system editing
  • visualization of scalar and vector data fields

CARPentry Studio operates at refresh rates unheard of by typical graphical applications. Even high-resolution whole-organ models are rendered at smooth 144Hz refresh rates.

Digital Twins

Ready-to-go digital twins

Jump-start your simulation workflows with our production-ready digital twin models. Let us generate new models, customized for your specific needs. Every digital twin comes with physiological region annotation, muscle fibers and anatomical reference frames and is accompanied by a CARPutils in-silico reference experiment for initial testing. Additional features, like His-Purkinje systems or medical devices can be integrated on demand.


He received an M.Sc. Degree in Electrical Engineering in 1996 and a Ph.D. degree in Biomedical Engineering in 2000, both from the Technical University of Graz, Austria. He has been a Postdoctoral Fellow at Technical University of Valencia, Spain (2000-2002), at the University of Calgary, Canada (2003) in the lab of Profs. Leon and Vigmond and, as a Marie Curie Fellow, he held a Visiting Faculty position at the Johns Hopkins University, USA (2006-2008) in the Trayanova lab. In 2008 he became Academic Fellow at the Oxford e-Research Centre and the Oxford Computing Laboratory at the University of Oxford, U.K before being appointed as Associate Professor in 2011 at the Medical University of Graz. Since 2018 he is Professor of Computational Cardiology and head of the Computational Cardiology Laboratory.

He received his M.Sc. and Ph.D. in mathematics and biomechanics from Graz University of Technology under the supervision of Prof. Olaf Steinbach and Prof. Gerhard Holzapfel. He has been Postdoctoral researcher at the Institute of Biophysics at the Medical University of Graz, Austria in the lab of Prof. Gernot Plank and as Marie Curie Fellow in the computational fluid mechanics lab of Prof. Shawn Shadden at Department of Mechanical Engineering, UC Berkeley. His main research interests are multi-physics problems, in particular the electro-mechano-fluidic modeling of the heart, and their numerical simulation using high-performance and massively parallel computing.

He has degrees in Biomedical Engineering from the University of Toronto. He was a professor at the University of Calgary for 10 years where he was also the Director of the undergraduate Biomedical Engineering Program. He has over 30 years experience in HPC modeling of electrophysiology. He collaborates with colleagues from all over Europe and North America, both clinicians and basic scientists. He has coauthored cardiac simulation code which is currently freely available, and used by several laboratories around the world to produce articles in top ranked journals. Edward Vigmond is one of the 5 members of the Steering Committee of the openCARP project.

He has received a PhD in Mathematics, under the supervision of Prof. Gundolf Haase, from the University of Graz in 2015 and has been a Postdoctoral researcher in the Computational Cardiology Laboratory at the Medical University of Graz from 2014-2019. In 2019 he co-founded NumeriCor GmbH and became its CEO. He has a background in High Performance Computing and Iterative Solver Methods, but his expertise also includes GPU computing, parallelization techniques, software architecture design and mesh generation techniques. He has been involved in international projects with KIT, the King’s College London and Medtronic. Aurel Neic is one of the 5 members of the Steering Committee of the openCARP project.
