An expanded description of these solvers will be given in §5.6.1.
Implemented a feature for finding an approximate reference configuration given a measured (deformed) geometry and boundary conditions.First experimental version to support solid element parts connected by *CONSTRAINED_SPR2.
3D Kink Cracked Version manual#
See the R13 keyword manual for further details.Ģ. Applications include seismic engineering and staged construction modeling. Added feature invoked with *CONSTRAINED_SOIL_PILE that enables modeling of piled foundations in soil/structure interaction models. Prior to this release, 2D existed but was experimental and under development.ġ.
Added new boundary condition keywords for acoustics: *BOUNDARY_ACOUSTIC_COUPLING_SPECTRAL, *BOUND-ARY_ACOUSTIC_FREE_SURFACE, *BOUNDARY_ACOUSTIC_IMPEDANCE_COMPLEX, *BOUNDARY_ACOUSTIC_IMPEDANCE_MECHANICAL, *BOUNDARY_ACOUSTIC_INTERFACE, *BOUNDARY_ACOUSTIC_NON_REFLECTING, *BOUNDARY_ACOUSTIC_PRESCRIBED_MOTION, and *BOUNDARY_ACOUSTIC_PRESCRIBED_SPECTRAL.Added keyword *CONTROL_IMPLICIT_SSD_DIRECT to request a direct complex solution to steady state vibration.Added keyword *CONTROL_ACOUSTIC_SPECTRAL to request an acoustic spectral element analysis.§5 New Features §5.1 Acoustics, NVH, and Frequency Domain In the interest of brevity, each item is listed only once, under a single category. Understand that in many cases, a particular item may pertain to more than one category. The items are arranged by category in the sections New Features, Improvements and Enhancements, and Bug Fixes. Some of the bug fixes may have also been included in other recent releases.
The remainder of this file provides a brief description of new features, enhancements, and bug fixes in version R13.0.0. The solvers described in this manual are intended for including manufacturing results in structure analyses.
With this release, we have a new manual: Volume IV Multiscale for analyses that involve multiple scales. Note that there may be features mentioned in the DRAFT User manual which are not implemented for R13.0.0. Until such time the R13.0 User manual is posted at the DRAFT User Manual may be used as a temporary substitute.
