More arguments are added in the UMAT and UCOHES subroutines for passing internal data, such as element Gaussian point volume, procedure phase and convergence flag. The user could define state variables for user material subroutines. This release enhances the capabilities of user defined materials. Patran Support for MSC Nastran User Defined Services / Subroutines (UDS) Along with the new contact pair user interface is a set of tools that allow users to automatically create contact bodies and contact pairs based on user-defined criteria. This capability, along with Patran's global property editing capability, provide a powerful, scalable UI that is suited equally well to creating both individual contact pairs, and large numbers of complex contact pairs, using common properties. The interface allows users to create contact pairs using individual contact property sets, or re-use existing interface definitions by referencing existing property sets. MSC Patran 2013 supports the new MSC Nastran 2013.1 contact pair user interface by providing a new Contact Pair Load and Boundary Condition (LBC) graphical user interface. Patran Support for MSC Nastran Contact Pair Modeling Patran 2013 provides support for the MSC Nastran Embedded Fatigue (NEF) capabilities including fatigue materials, load event manipulation, and post-processing, which is provided for using standard MASTER/DBALL attachments, or through the new OP2 file. Patran Support for MSC Nastran Embedded Fatigue (NEF) The new OP2 format supports the latest SOL400 results quantities including contact results, Nastran embedded fatigue results, and user defined service and subroutine results. In addition to supporting Direct Results Access (DRA) attachment of the results via Patran, the file browser menus have been modified to the correct defaults which allow for OP2 import or DRA attachment. Patran 2013 provides enhanced post-processing support for MSC Nastran by supporting the new OP2 (obtained using PARAM,POST,1) format. MSC Nastran OP2 New (PARAM,POST,1) Format This includes post-processing MASTER/DBALL, XDB, and OP2 results files generated by MSC Nastran 2013.1. Patran now supports the most recent version of MSC Nastran available at release time which is MSC Nastran 2013.1. Some of the new capabilities in this release include: Patran 2013 delivers several ease of use enhancements for structural analysis and durability applications in aerospace, automotive, and other non-transportation industries. MSC Software Corporation, the leader in multidiscipline simulation solutions that accelerate product innovation, announced the release Patran 2013, its most widely used pre/post-processing software for Finite Element Analysis (FEA).
