Abstract
A rapid error checking method of geological model in civil engineering is proposed based on hexahedral finite elements. Firstly the node and element index information of each unit is split into six space surfaces, then it is divided into common surface element and special surface element, by means of the coordinates of nodes and topological relation errors is self-checking and all special surface element is written to AutoCAD by 3DFACE in order to locate the errors. The case analysis shows that the method is in high efficiency, which can make the model errors appearing at the same time, then help to modify the geometry location in numerical model. This method can cost little time and avoid the calculation distortion caused by improper connection results, and is a effective tool for pretreatment of continuous numerical simulation.
