UDM Library

Itasca is pleased to provide a collection of selected User Defined constitutive Models (UDM) for Itasca software (FLAC, FLAC3D, UDEC, 3DEC, and PFC). The usage of the UDMs available at this site is free of charge. However, the C++ UDM option for the corresponding Itasca software product, available for purchase, is required.

Itasca clients interested in contributing their own UDMs are invited to submit them.

Please note that the UDMs are provided for your convenience, as is, and Itasca takes no responsibility for the correctness or your usage of the UDMs.
