Release of the AnyBody Modeling System™ Version 4
AnyBody Technology is proud to release a Version 4 of the AnyBody Modeling System™. The full list of new developments and features in Version 4 is available in the release notes. Below you find descriptions of two of the main developments in Version 4, the muscle recruitment algoritms, and the graphical user interface including Model View.
Download the new software here. New users are encouraged in tour the software by going through the Getting Started tutorial. Existing users who are eligible for upgrades will receive their new license keys within few weeks. For those who are eager to get started with Version 4, you can download the demo instantly.

Improved Muscle Recruitment In biomechanics, inverse dynamics is traditionally understood at the process of computing from measured ground reaction forces in a gait analysis to net moments in the anatomical joints. However in AnyBody context, inverse dynamics is much more than that. In brief, inverse dynamics allows you to simulate muscle and joint forces in the entire body undergoing complex movements, taking dynamic inertia forces in to account, and not necessarily requiring measured forces in the interface between the body and the environment.
Key to this when working with sophisticated, large model like ours is the muscle recruitment methodology which has been completely reworked in the new version 4.
The understanding of this problem and how it is dealt with in the AnyBody Modeling System™ is so important that an entire new tutorial named Inverse dynamics of Muscle Systems has dedicated to the problem and the physiological assumptions behind it. Lesson 1 deals with The basics of muscle recruitment, Lessons 2 thru 5 deal with Linear, Quadratic, Polynomial, and Min/Max muscle recruitment criteria, respectively, and, finally, Lesson 6 explains about model Calibration. |

Improved graphics and interface
The key feature in the new Model View is that interaction with the model appearance in the Model View is now possible. In the first release of this it allows simple manipulations without acting through drawing objects in the AnyScript code. In short, we now have a platform which will allow users to interact with the model by clicking the Model View. The full list of new developments and features in Version 4 is available in the release notes. |

License types and licensing options available with Version 4
Four license types aimed for different types of users are available with version 4: - Standard Licenses for commercial entities and institutions doing classified research
- Non-Faculty Research Licenses for research aimed at publication at government agencies and non-profit institutions
- Faculty Research Licenses for teaching and research aimed at publication at academic institutions
- Student Licenses for student’s education. Please refer to the End User License Agreement in the software for the exact details.
For Standard, Non Faculty Research, and Faculty Research Licenses users have the choice of either floating or node-locked licenses. Student Licenses are only available in batches as floating licenses (10, 20, or 50 licenses by default).
Software Maintenance subscriptions are offered for 1, 2 or 3 years (with a discount for 2 and 3 years). Also, subscribers to Software Maintenance get access to the AnyBody Managed Model Repository. | |
Campaign offer: License fee and upgrade discounts
In association with the release of the version 4 major software update we are pleased to offer new customers significant discount on the initial license fee! Please inquire here.
Discounts are also available to existing customers extending their software maintenance subscription. Please inquire here.
The campaign will run onto June 30th, 2009. | |

Meet us at booth # 732 and learn what AnyBody Technology can do to improve your spinal implant solutions. | |
Spine surgery: How muscle damage affects joint loading
Surgical interventions often alter the mechanics of the body. Removing even a small muscle might completely change the loads on an implant or joint, detrimental to patient recovery and quality of life. With AnyBody you can investigate how surgical interventions affect the mechanics of the body.
In this simulation a case of spine surgery is investigated. The standard standing model from the AnyBody Repository has several muscles partly removed (by reducing their strength). The affected muscles are 19 branches of the Multifidi and 6 branches of the Longissimus Thoracis (part of the Erector Spinae). The effect of these changes on the compression force and medial/lateral shear force in the L5-Sacrum joint is depicted in the charts and in this animation.

Job opportunity in Knee Model Development
An appointment as an Experienced Researcher (ER) within the framework of the European Marie-Curie Research and Training Network entitled 3D Anatomical Human is available at Center for Sensory-Motor Interaction (SMI) at Aalborg University, Denmark. The main task lead by SMI is to perform experimental analysis of human movement to support the development of the models. A second task is to develop a detailed knee model using the AnyBody Modeling System in close cooperation with the AnyBody Research Group.

Job opportunity: 2 PhD fellowships, one for model validation and one for posture and movement prediction
Validation of musculoskeletal models of the human body
The Department of Mechanical Engineering at Aalborg University, Denmark, is looking to fill a PhD stipend within the general study program "Mechanical Engineering". The purpose of the project is to investigate and develop reliable methods for validation of musculoskeletal models of the human body against experimental results. The project is therefore inter-disciplinary in nature comprising elements from mechanics and physiology and a combination of experimental and computational work.
The fundamental problem that the project addresses is that the output of musculoskeletal simulation models, i.e. muscle and joint forces, are very difficult to measure in-vivo, and the necessary validation of the models is therefore a problem, which likely must be solved by a variety of means.

Human posture and movement prediction based on musculoskeletal modeling
The Department of Mechanical Engineering at Aalborg University Denmark, is looking to fill a PhD stipend within the general study program "Mechanical Engineering". The purpose of the project is to investigate and develop reliable methods for prediction of natural postures and movements by means of musculoskeletal models of the human body. The project is therefore inter-disciplinary in nature comprising elements from mechanics, numerical mathematics, software development and physiology. The hypothesis of the project is the idea that voluntary postures and movement strategies in humans are guided by a desire to optimize performance according to some criteria. It is the purpose of the project to identify these criteria, cast them into a mathematical form and implement them in musculoskeletal models using the AnyBody Modeling System.
