User-Defined-Models for the Itasca Codes FLACFLAC3D, UDEC, 3DEC, PFC2D and PFC3D

This site is maintained by Itasca Consultants GmbH and contains a collection of selected User Defined constitutive Models (UDM) for Itasca software.

The usage of the UDMs available at this site is free of charge. However, the CPPUDM-option for the corresponding Itasca code is required, which can be purchased. Please contact your software agent.

Two different groups of UDMs exist:

for the codes FLAC, FLAC3D, UDEC and 3DEC
for the codes PFC2D and PFC3D

Itasca code users, who have developed their own UDM, are strongly encouraged to contact us for having their UDM added to this site. The source code of the UDM will be included in the download file, if the developer / client agrees with the publication.

Itasca takes no responsibility for the correctness and the usage of the UDMs. For details please refer to the liability section.

For further information on Itasca or our software products, please check our website.
