METSIM® version 2021.02 is now available online at

Major developments include the addition of new programs allowing for METSIM® to communicate with external data sources, such as text and comma separated variable files. A vast improvement to Dynamic Data Exchange, this feature provides the ability to link METSIM® models with nearly any other data source or software without the need to have these external files or programs open. Many METSIM® users are already utilizing these features to achieve Digital Twins in their operations, aiding in control room simulations and detailed operator training packages. Several minor program bugs have also been addressed.

Take note that the file size restriction in previous versions of METSIM® was removed in v2020.06, allowing for the creation of very large and complex model files.

For a complete list of updates available in METSIM® v2021.02, please contact a technical or sales agent in your region.
