Defining and apply a gravity load in Abaqus

Hi geys in this article i need to show you how to creat gravity load simulation in Abaqus .
The first  you should to fine the density of matérial you need to be self weighted load for calculating the weight(mass).
You can create a gravity load to define a uniform acceleration in a fixed direction. A gravity load is applied to the whole model. ABAQUS calculates the loading using the acceleration magnitude that you enter in the gravity load definition and the density specified in the material definition.
To create or edit a gravity load:

Display the gravity load editor using one of the following methods:





To create a new gravity load, follow the procedure outlined:
Creating loads (Category: Mechanical; Types for Selected Step: Gravity).




To edit an existing gravity load using menus or managers




In the Component 1, Component 2, and (if you are working with a model in three-dimensional space) Component 3 text fields, enter the components of the acceleration in each direction:





If you are working in three-dimensional or two-dimensional space, the Component 1, Component 2, and Component 3 fields correspond to the 1-, 2-, and (if applicable) 3-directions.




If you are working in axisymmetric space, only the Component 2 text field is available. Component 2 corresponds to the axial direction.
If you leave a text field blank, a value of zero is assigned to that direction automatically. However, you must enter at least one nonzero component in the editor to define the load.




If desired, click the arrow to the right of the Amplitude field, and select the amplitude of your choice from the list that appears.




Click OK to save your data and to exit the editor.

Exemple of applying gravity in the Load Module.
 -->Load,Create,(go down in the menu) Gravity is about in the middle, and put -9810 [mm/sec] into y direction-box, if your gravity is in that way. Click OK, and you applied the G to your whole assembly.
