ANSYS WORKBENCH 14: Simply support option disabled

Click For Summary
SUMMARY

The discussion focuses on the inability to enable the simply support option in ANSYS Workbench 14 (WB14) for a beam modeled as a 3D solid element. Users are advised that the simply supported boundary condition is typically applicable only to line or shell elements, not to 3D solids. To address this limitation, the suggestion is made to either use beam elements or apply remote displacements to constrain the beam's motion. This approach allows for accurate simulation of the beam's deflection under uniform distributed loading due to its own weight.

PREREQUISITES
  • Understanding of ANSYS Workbench 14 (WB14) interface and functionalities
  • Familiarity with finite element analysis (FEA) principles
  • Knowledge of beam theory and structural loading conditions
  • Experience with CAD modeling and importing IGS files into FEA software
NEXT STEPS
  • Learn how to model beam elements in ANSYS Workbench 14
  • Research the application of remote displacements in ANSYS for boundary conditions
  • Study the differences between 3D solid elements and line/shell elements in FEA
  • Explore uniform distributed loading scenarios in structural analysis using ANSYS
USEFUL FOR

Engineers, structural analysts, and FEA practitioners who are working with ANSYS Workbench 14 and need to understand boundary conditions for beam analysis.

Hello..

i am trying to determine the maximum deflection of a beam on account of its sagging due to its own weight.
I have the CAD MODEL of the beam and i import its IGS into ANSYS WB14.static structural.

1.is it a uniform distributed loading case?

2.i need to simply support the beam at both ends..but when i select the lower edge of the beam and goto SUPPORTS i find that the simply supported option is there but DISABLED(greyed out)..what to do now?

3.i need to apply the loading..how to go about this?

THIS IS NOT A HOMEWORK PLEASE!..
 
You could have easily used hand calculations for the same, why do you need FEA?

Also, how about just use plane line (beam) elements instead of full 3d structure?

Simply supported option (probably) only works for line (& possibly shell) elements. It does not work for 3d solid elements.

Or if you really want to use your CAD , try remote displacements in which you can constrain linear and rotational motions along each axes.
