Adaptive Mesh Refinement Method Suitable for CFD Analysis of WindEnvironment around Buildings

In order to generate effective grid for CFDanalysis of wind environment around buildings in urban area, we newly develop non-uniformtype adaptive mesh refinement method(NUAMR). Different from the conventionaluniform type AMR (UAMR), NUAMR won'tsmooth mesh outside a windward stream tube ofa target region. By comparing overallperformance between UAMR and NUAMR, wereveal NUAMR method's advantage as listedbelow: 1) NUAMR method and UAMR methodhave almost same accuracy in wind velocityratio around a high-rise building. 2) NUAMR method can automatically generatecomputational cost-effective mesh that has much smaller number of cells than UAMR method creates.
