The surface wrapper leak detection tool is useful for determining whether "leaks" exist in the either the import surface or the wrapped surface. A leak is a gap or a hole that would allow a path to be traced from one volume through to another volume or the outside without crossing through a surface. Therefore a fully enclosed surface has no leaks.
The leak detection tool is accessed by right-clicking on the Surface Wrapper model node in the simulation tree and selecting Run leak detection... in the pop-up menu:
The Wrapper Leak Detection dialog will appear, as shown below:
Two separate points based on the global cartesian system need to be defined. One of the points should be inside the volume of interest and the other outside of it (in another volume if necessary). Activating the Display Tool option allows the two points to be selected graphically on the display by dragging the two balls to the appropriate locations. Pressing the Apply button invokes the scheme and detects whether a leak exists between the two points. An example leak path is shown below:
A summary of the leak detection calculation is reported in the Output window. A typical example is shown below:
If a leak is detected then it will report back that a path has been found between the two points. If there is no leak, then no leak trace will be displayed and a message saying that no path was found between the two points will appear in the Output window.
The leak detection option can be run either prior to the wrapped surface being made or afterwards. The leak detection tool accounts for the current wrapper settings and determines if any gaps in the import surface would be closed based on the gap closure settings. If the sizes specified are not sufficient then it will report back with the leak path.
