FEM ConstraintSelfWeight/ru

Описание
Defines a gravity acceleration of 9,81 m/s^2 acting on the whole model in the prescribed direction.

Применение

 * 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 gravity load by changing its vector coordinates in the property bar of the newly created ConstraintSelfWeight object.

Limitations

 * You need to modify the .inp file to edit gravity acceleration.
 * Self-weight is applied to the element set Eall which includes the whole model.

Editing CalculiX input file
The acceleration constant can be manually edited after generating the CalculiX input file.

Example of lines in the .inp file:

where 9810 is a gravity acceleration magnitude in [mm/s^2], and 0,0,-1 is the direction vector.
