FEM ConstraintSelfWeight/de

Beschreibung
Die Randbedingung Eigengewicht legt fest, dass die Erdbeschleunigung von 9,81 m/s^2 auf das gesamte Modell in der voreingestellten Richtung wirkt.

Anwendung

 * 1) There are several ways to invoke the command:
 * 2) * Press the button.
 * 3) * Select the option from the menu.
 * 4) You can modify the direction of gravitation by changing its vector coordinates in the property bar of newly created ConstraintSelfWeight object.

Scripting

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 magnitude in [mm/s^2], and 0,0,-1 is direction vector.
