FEM ConstraintSelfWeight/en

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 [[Image:FEM ConstraintSelfWeight.png|32px]] or choose  →    from the top menu or press  then  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:

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