On occasion of the World Thyroid Day on May 25th, 2014, a new version of SimThyr has been released. SimThyr is open source software for simulation of thyroid homeostasis (hypothalamus-pituitary-thyroid feedback control).

Version 3.3 of SimThyr adopts the most recent version of PUMA Unit Converter, which replaces an older custom solution in SimThyr. The PUMA module has been extensively tested and is regularly updated. Therefore, using the Unit Converter promises a higher reliability of the overall application.

Conversely, special requirements of SimThyr, a computation-intensive application, necessitated the advancement of the Unit Converter. Due to SimThyr's needs it now introduced new functions for pre-calculating conversion factors for time-critical applications.

SimThyr 3.3 is available for free from http://simthyr.sf.net for Linux, Mac OS X and Windows.
