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 whole model.

Changing gravity acceleration

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]
