In the first code fragment taken from the ds.dat file, we see a SOLVE for a displacement analysis. The reswrite command in the ds.dat file appends the result in database memory to whichever RST file is specified. Four code fragments of the ds.dat file are shown. In the following example, Displacement, Velocity and Acceleration results have all been requested in Analysis Settings. The structure of an example ds.dat file for a Response Spectrum analysis illustrates the formation of the Displacement, Velocity and Acceleration results. Acceleration results are saved in Load Step 4, Substep 3. Velocity results are saved in Load Step 4, Substep 2. Examination of v14.5 models shows that with a Response Spectrum Analysis, the displacement results are saved in the RST file as Load Step 4, Substep 1. Response Spectrum Analysis | Ansys Batch Runĭuring the Batch Ansys run that reads in the ds.dat file generated for an environment by Workbench Mechanical, results are saved in the RST results file in the folder for the environment. Analysis Settings can be used to indicate whether in addition to the displacement that is automatically generated, a user would like to have Velocity and/or Acceleration results generated: In single-point response spectrum analysis, an excitation input of Response Spectrum Displacement, or Velocity, or Acceleration can be added as an object in a Response Spectrum environment.Ī global direction for the excitation is entered, and it is applied to all constrained nodes during the SOLVE. In a Response Spectrum Analysis, Workbench Mechanical permits description of supports (zero displacement boundary conditions) in the Modal environment. Response Spectrum Analysis | Model Settings This article illustrates where information can be obtained with postprocessing APDL Commands Objects after a Response Spectrum Analysis. Users sometimes want to use APDL Commands Objects in postprocessing to extract results data and create Output Parameters. Depending on the results requested in Analysis Settings for a Response Spectrum solution, velocity and acceleration results can be obtained, in addition to deflection, stress and strain. Either single-point or multi-point response spectrum analysis can be performed. Using APDL Commands Objects in Postprocessing to Extract Data and Create Output ParametersĪnsys Mechanical Workbench supports Response Spectrum Analysis.
