Finite element mesh generation algorithm often requires the ability to abstract and modify the topology of a boundary representation model. A method based on virtual geometry for mesh generation is proposed to modify the model topology without changing the geometry of the model. By this method, a tool is given to adjust the model topology for optimal meshing, while leaving the geometry or shape of the model, and the accuracy of the resulting mesh in representing the model, unchanged. Our practical examples show that the proposed method is effective and reliable for mesh generation in molding analysis field.
