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.
