Contam軟件使用基本方法

1、COANTAM軟件基本操作方法及實(shí)例首先，畫出需要分析建筑物的基本輪廓，尺寸大小等打開(kāi)Contam軟件后，開(kāi)始建立建筑物的物理模型。第一步：設(shè)置Level屬性，“EditLevelData”層高基本設(shè)置為3米第二步：利用Tool中的畫圖命令繪制建筑物體的墻體，根據(jù)建筑實(shí)際情況，將建筑劃分為若干區(qū)域，然后，在各個(gè)區(qū)域中點(diǎn)擊鼠標(biāo)，按鼠標(biāo)右鍵菜單中的“Zone”,創(chuàng)建區(qū)域（創(chuàng)建后，會(huì)在相應(yīng)的區(qū)域中出現(xiàn)紅色標(biāo)記“回”，紅色意味著還沒(méi)有對(duì)該區(qū)域進(jìn)行屬性定義），然后對(duì)各個(gè)區(qū)域的屬性（如尺寸大小，室內(nèi)溫度等）進(jìn)行定義，如下圖：道進(jìn)行屬性定義，如下：、ModelSurnrridryFlowPathWirLdP
