Advanced: At right side of the property section there is advanced button, by clicking it you will get the following two fields:
Distribution: You can specify how you would like to distribute load along the selected reference entities.
If you select total load option then you have to specify the value of the sum of the loads applied to all the selected entities and ProE mechanica will equally distribute the amount of loads.
If you go with the Force per unit area/length option then you have to divide the total loads to the area or length.
There is another option available called total load at a point. In this case you have to select the point as well where you want the total loads to be acted. This will create a distributed load over the reference curve or surface which is statically equivalent to the resultant load at specified point.
You cannot select this option for 2D axisymmetric model.
Spatial Variation: Sometimes the magnitude of load may vary over the reference entities, this variation can be controlled by these options.
If your force magnitude is uniform throughout then go for uniform option.
When there is a complex variation of the magnitude then you can think of using the option function of coordinate to define this type of load. This will be discussed more later on.
There is one more way to define the magnitude variation of applied load, which is Interpolated over Entity. If you click on this option you will get a define button. Click on it in order to select the points (minimum two) where you can enter the interpolation factor.
For example if you select two points of a reference curve and at the first point if you put “1" and at the second point“2" , then at the first point the magnitude of the load will be the specified value of load (say 100) multiplied by “1" and at the second point it will be the specified load value (100) multiplied by “2" and your load distribution along the curve will gradually increase from 100 at one end to 200 at the other end. This also works similarly for surface.
