From the existing theory of the random medium model, every single local maximum point of a continuous random medium as the center point of each cave distribution area was taken, the two model characteristic quantities namely the local radius R and the local density p were introduced, simulated all sorts of different random cave medium models by the.

The boundary layer effect of the powder injection molding filling flow process was studied through local density measurement and SEM.

A parallel algorithm of local mesh refinement solving the singular two-point boundary value problem based on PVM;

To any complex border situation, the quadtree finite mesh generator works quickly and efficiently, and can realize adapativity, local mesh refinement and sparseness conveniently.

This paper discusses high precision methods of the interpolation correction of finite element for elliptic eigenvalue problems, and combines grid local refinement (r-refinement) with the interpolation correction scheme to obtain a higher precision in the reentrant corner.

A local refinement method of unstructured grid generated by bubble packing method(BPM) is proposed.

It has been found that the lognormal law, normal law and negative index law for the local accumulation of the diffusible hydrogen occured in the fusion zone, and the juncture of coarse grained and fine grained zones.
