The following script example checks the Units setting in a Workbench Mechanical solution run, and works because the /UNITS command is executed by the Ansys input APDL job ds.dat file that Workbench Mechanical creates. Default is the Active System Units from the Menu, but the Analysis Settings Details takes priority if set to Manual:Īnsys Workbench General Item and Component Labels If an APDL Commands Object assumes units during SOLVE for loads, material properties, contact settings, or makes other units-related assumptions during customized pre- or post-processing, it is critical to use the correct system of units.Ī second control for Units during SOLVE is set in Details of each environment’s Analysis Settings. Consider a material property in a Commands Object using the BIN system of units (lb-in-sec), but UNITS in Workbench Mechanical set to SI. It is easy to have the wrong UNITS chosen when Workbench Mechanical SOLVE executes, for a Commands Object that assumes a particular system of units. What are the default units used in Ansys APDL? Note that the SI system is “newer” than the MKS system, with some differences in electronic units. Table 146: *GET General Items, Entity = ACTIVE The *GET command supports identification of the /UNITS setting employed: UNITS, Label, LENFACT, MASSFACT, TIMEFACT, TEMPFACT, TOFFSET, CHARGEFACT, FORCEFACT, HEATFACTĪnnotates the database with the system of units used.

Note that /UNITS is merely a recording device. Users are advised to check the Commands Manual for the /UNITS command.

Workbench Mechanical has several systems of units for a user to choose.

The check could be included at the beginning of any APDL Commands Object in Workbench that assumes the UNITS employed in a SOLVE. This article illustrates how to use APDL commands to detect the UNITS that are active when SOLVE is requested for an environment in Workbench Mechanical. Industrial Equipment and Rotating MachineryĪnsys Workbench Mechanical supports the presence of APDL commands in the Outline so that user-programmed commands will act on a model at the Body, Connection, Solver or Postprocessing stage of an Ansys job running from the ds.dat file generated by the Mechanical SOLVE command.Torsional Vibration Measurements Testing.Fluid Flow & Thermal Applications (CFD).
