For this example we will use a pool model as shown in the following figure.
The water level is 1m below the upper edge of the pool walls.
To automatically generate the water pressure from the pool walls we need to use the “Pressure generator”. This tool is accessed from the main menu bar: “Generate / Load / Pressure…”
This command will open the pressure generator window:
The following options are available:
As seen from the figure above, the pressure loads for some elements are pushing from the outside of the pool. This is because of the orientation of the local Z-axis of these elements.
As we can see, for the plane elements 2 and 3, the local Z-axis is orientated to the outside of the pool and the local Z-axis of element 1 is orientated to the inside of the pool.
There are two ways to correct this:
2. Individually select each of the incorrectly oriented loads and from the properties list change the orientation by changing the sign.
In the end all the loads should be orientated from the inside to the outside of the pool.
