More and more attention has been paid to unstructured adaptive grid for its distinguished advantage in dealing with complex boundary conditions 自適應(yīng)非結(jié)構(gòu)網(wǎng)格因其在處理復(fù)雜外形問(wèn)題上的顯著優(yōu)勢(shì)而受到越來(lái)越多的關(guān)注。
The model system is in the generalized curvilinear coordinates , using high precision self - adaptive grids to fit the complicated topographies and coastal shapes 模型系統(tǒng)采用廣義曲線坐標(biāo)系下的形式,使用高精度的自適應(yīng)網(wǎng)格擬合復(fù)雜岸界。
Based on the computational results for the initial grid division , the adaptive grid refinement is introduced until meeting the required accuracy . the computer program is established for implementing the aims described above 在對(duì)初始網(wǎng)格進(jìn)行初步的流場(chǎng)計(jì)算的基礎(chǔ)上,根據(jù)計(jì)算結(jié)果對(duì)網(wǎng)格進(jìn)行自動(dòng)加密,直到流場(chǎng)模擬結(jié)果達(dá)到規(guī)定的精度要求。
The primary objective of this dissertation is to establish a self - adaptive grid division and refinement scheme and successfully apply it to the numerical simulation of wind flow around buildings and building complexes 本文的主要目的是提出并建立起一套能在計(jì)算過(guò)程中自適應(yīng)調(diào)整的網(wǎng)格離散與加密方案并成功應(yīng)用到單體及群體建筑風(fēng)場(chǎng)的數(shù)值模擬中。
Thirdly , the interacting multiple model is analyzed for maneuvering targets tracking . more and more models are added to the imm algorithm for a better tracking precision , at the same time , this brings huge computation burden . for this reason , we mainly studied the adaptive grid interacting multiple model and 因此,我們?cè)诙嗄P蜋C(jī)動(dòng)目標(biāo)跟蹤研究的基礎(chǔ)上,針對(duì)現(xiàn)有算法跟蹤高機(jī)動(dòng)目標(biāo)存在的問(wèn)題,提出了一種基于分段航跡識(shí)別的新的機(jī)動(dòng)目標(biāo)跟蹤方法,該算法具有一定的創(chuàng)新性。
A ceremony was held in beijing , during which the amss director , professor guo lei , presented the appointment letter to professor tang . the honour was in recognition of his " significant contributions to numerical methods for incompressible flow simulations and hyperbolic conservation laws , especially for the development of moving mesh adaptive grid computations . 聘書(shū)頒發(fā)儀式在北京舉行,由郭雷院長(zhǎng)親自頒發(fā)。該項(xiàng)殊榮是嘉許湯教授在不可壓流體和雙曲守恒律的計(jì)算方法,特別是自適應(yīng)移動(dòng)網(wǎng)格方法等方面作出重大的貢獻(xiàn)。
