针对摸个引用，能够分离有限元模型的表面。-It can be useful to separate the surface of a finite element model for certain applications such as fatigue analysis. For example, if cracks are known to initiate on the material surface, then the inclusion of sub-surface elements can slow down the analysis unnecessarily.

This algorithm identifies the surface elements of a model by looking at the contents of an Abaqus RPT file. Therefore, the file getRPT is required.

detectSurface only works for brick elements. Users should also make sure that the RPT file is defined as an element-nodal listing.

IMPORTANT: Users should ensure that the field output file is sorted by node label as opposed to element label. This is done in the Abaqus Visualization Module by going to　Report-> Field Output...-> Setup　and choosing　Sort by: Node Label　within the Output Format options.

For help creating an RPT file, see the help section for getRPT.
