Defining a variable load on a linear element • Select the linear element.

• Launch the load creation command, either from the menu Modeling > Create a linear load, or from the element's context menu: "Load / selection". • Define the load intensity and orientation in its properties window. Select "local axes" in the Coordinate System field, to specify that the load be applied in the element's local axes. • Enter the load variation coefficients along the linear element.

- "Coefficient1" defines the load intensity at the first extremity of the linear element. The coefficient 1 specifies that load is applied at the fist extremity of the elements with full intensity (-20kN).

- 0.5 for "Coefficient2" specifies that the load is applied with half intensity at the second extremity of the element (-20kN x 0.5 = -10kN).

- The load is applied at the first extremity of the linear element at -20kN (1×20kN), with a linear variation to the second extremity, where the force is applied with -10kN (0.5×20kN). Defining a variable load on a planar element • Create a planar load in a similar way as for the linear load. • Enter the load intensity in the properties window and select "local axes" as the reference coordinate system. • The load variation on the planar element is specified by three coefficients: "Coefficient1", "Coefficient2" and "Coefficient3". These values define the force intensity applied at the first three points of the planar element. The load will have a linear variation toward the two axes of the planar element (x,y). • When the three variation coefficients have the same value, the load is equally distributed on the element's surface.

• In the cases when the variation coefficients values are different:  Related Products Graitec Advance Design
