HyperWorks Solvers 2017.2.1 릴리즈

HyperWorks Solvers는 구조, 유체, 동역학 및 시스템 시뮬레이션 등을 위한 유한 요소 기반의 첨단 솔버 패키지입니다. 이 솔버들은 다양한 분야에 대한 시뮬레이션 및 최적화에 사용되고 있습니다.

이번 HyperWorks Solvers 2017.2.1 핫픽스에서는 OptiStruct, RADIOSS에 대한 성능 향상, 버그 수정이 포함되어 있습니다.

자세한 내용은 릴리즈 노트를 참조하시기 바랍니다.

HyperWorks Solvers 2017.2.1 공식 업데이트의 상세한 내용은 아래와 같습니다.

OptiStruct 2017.2.1

Enhancements

  • The SURF option is now available for the SUBTYPE field of SET Bulk Data Entries for TYPE=GRID/ELEM to automatically identify the grids or elements on the surface of the entire model or part of the model, based on selected properties (the optional property ids can be specified in continuation line of such SET). The identified grid points or elements form a set which can then be used wherever required, for example, as PANEL definition in ERP output.
    Example:
    SET 1 GRID SURF -> SET of grids for surface of entire model
    SET 1 ELEM SURF -> SET of elements for surface of property id 10
    + 10
    If the model is a solid model, then the solid elements (or grid points) belonging to the topmost layer of the model are identified as part of the set.
  • SMOOTH option is now supported for Node-to-Surface Continuous Sliding Contact.
  • For CONTACT analysis, ADJUST/CLEARANCE option can be used together with SMOOTH option.
  • Output of the Absolute Maximum Principal Stress for Random Response Analysis can now be controlled using PARAM,PSDPRINC,YES/NO. The Absolute Maximum Principal Stress for Random Response Analysis is output only if PARAM,PSDPRINC,YES is present in the the input file.
  • The performance of Topology Optimization with Overhang Constraints has been enhanced.


RADIOSS 2017.2.1

Resolved Issues

  • 1D elements (de)activation with sensors: activation and deactivation of 1D elements might not work. Most of the crash models with safety belts use sensors to (de)activate springs.
  • Length of parameters names: parameters substitution might be random if parameters names exceed 9 characters (8 characters if the parameters is used with “–“ sign). Starter is now checking the length of parameters names; it will issue:
    o a WARNING if length of parameter name is > 8 characters
    o an ERROR if length of parameter name is > 9 characters
  • //SUBMODEL compatibility: enhanced pulley spring with asymmetric friction model (/PROP/TYPE12 + Ifric, Fmin, Fmax) was not compatible with //SUBMODEL.
  • Restart file size: Restart file size was significantly larger than normal.
  • /OUTP/ELEM/USER[1-5]: Possible Engine core dump at the first cycle if /OUTP/ELEM/USER1 to /OUTP/ELEM/USER5 is requested.
