Embodiment Construction
[0018] A method for adaptively modifying surface normal vectors in electromagnetic scattering simulation modeling, the steps are as follows:
[0019] The first step is the creation of surface subdivision files. Use subdivision software such as ANSYS, GMESH, etc. to subdivide surface elements (take triangular units as an example) on the surface of the object. At this time, the normal components of surface elements of the outer surface of the object obtained may be chaotic.
[0020] The second step is the formation of volume segmentation information. Use subdivision software such as ANSYS, GMESH, etc. to subdivide the voxel (take tetrahedron as an example) of the object. When subdivision software such as ANSYS and GMESH cannot perform volume subdivision for relatively complex models, the surface element information is imported into tetgen software to form an internal tetrahedron. So far, all subdivided volume and surface element information have been obtained.
[0021] The th...
