Description
Constraint self weight defines gravity acceleration 9,81 m/s^2 acting on the whole model in the prescribed direction.
How to use
- Click on or choose FEM → Constraint self weight from the top menu or press C then W keys.
- 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]
