Description

Constraint self weight defines gravity acceleration 9,81 m/s^2 acting on the whole model in the prescribed direction.

How to use

  1. Click on FEM ConstraintSelfWeight.png or choose FEMFEM ConstraintSelfWeight.png Constraint self weight from the top menu or press C then W keys.
  2. You can modify the direction of gravitation by changing its vector coordinates in the property bar of newly created ConstraintSelfWeight object.

Limitations

  • You need to modify .inp file to edit gravity acceleration.
  • Self weight is applied to the element set Eall means to the whole model.

Solver specific informations

CalculiX

Acceleration constant can be edited by hand modification after generating CalculiX input file.

Example of lines in .inp file:

*DLOAD
Eall,GRAV,9810,0.0,0.0,-1.0

where 9810 is gravity acceleration in [mm/s^2]
