MSC.Patran v2005 R2 MSC.Dytran Preference Enhancements January, 2005

S3-2 Materials and Properties Enhanc. Support local coord of centre of gravity in MATRIG Support for SHREX entry Support for YLDEX entry Support for HGSUPPR entry Reader support for all materials and properties MSC.Dytran Preference

S3-3 MSC.Dytran Preference Support local coord of centre of gravity in MATRIG Lists all existing MATRIG New button Add CID to MATRIG… added in Analysis -> Execution Controls… Note: Coord system must be different than the global coord system and the MATRIG must be defined with the optionmenu Rigid Body Properties set to Defined.

S3-4 MSC.Dytran Preference SHREX – User Specified Shear Model Materials -> Isotropic -> NonLinElas (DMAT) Available only if Shear Model is set to Polynomial New in 2005r2 Note: For Materials -> Isotropic -> NonLinPlas (DMAT) see next slide

S3-5 MSC.Dytran Preference YLDEX – User Specified Yield Model Materials -> Isotropic -> NonLinPlas (DMAT) Yield Coeff. available only if Yield Model is set to Polynomial New in 2005r2 Note: Shear Coeff G* available only if Shear Model is set to Polynomial

S3-6 MSC.Dytran Preference HGSUPPR – Hourglass Suppression Method Properties –> 2D -> Shell (All options except CO-TRIA) Properties –> 2D -> Membrane Properties –> 3D -> Lagrangian Solids For 2D Shell and membrane add: [Hourglass Supression Method] with options String/F-B Viscous/Dyna [Inplane Hourglass Damping Coefficient] – Real Scalar [Warping Hourglass Damping Coefficient] – Real Scalar [Twisting Hourglass Damping Coefficient] – Real Scalar For 2D Shell Homogeneous KeyHoff add also: [Rigid Body Rotation Correction] with options String/Yes/No [Time Step for Correction] - Real Scalar For 3D Lagrangian Solids add: [Hourglass Supression Method] with options String/F-B Stiffness/Dyna [Hourglass Damping Coefficient] – Real Scalar NOTES: The id of the HGSUPPR entry (HID) will be the same as the id of the property (PID). The Property type (TYPE) will be SHELL for 2D or SOLID for 3D.
