MagTense development has been sponsored by the Carlsberg Foundation Semper Ardens Advance project CF24-0920 entitled "Novel magnets through interdisiplinarity and nanocomposites", by the Villum Foundation Synergy project number 50091 entitled "Physics-aware machine learning", by the Independent Research Fund Denmark, grant “Magnetic Enhancements through Nanoscale Orientation (METEOR)”, 1032-00251B, by the Poul Due Jensen Foundation, in the project "Browns paradox in permanent magnets", project nr. 2018-016, by the Independent Research Fund Denmark project, contract. no. 7017-00034. Previously the development of the demagnetization part of the framework has been partly financed by the ENOVHEAT project, which is funded by Innovation Fund Denmark (contract no. 12-132673), and also the Programme Commission on Energy and Environment (EnM) (contract no. 2104-06-0032) which was part of the Danish Council for Strategic Research.
