FEM ConstraintSelfWeight/ru

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 → Mechanical Constraints →   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.

Scripting

 * new object


 * add object to the analysis named Analysis


 * example:

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.

Editing CalculiX input file
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]
