<p class="has-black-color has-text-color has-link-color wp-elements-4ab86509ecc34a3fe9458f8ffe312be1"><strong>Advantages of Using PreonLab</strong></p>



<p class="has-black-color has-text-color has-link-color wp-elements-251c7f21812139930e285bffa882103d">PreonLab is a meshless CFD analysis tool that avoids the complexities of traditional preprocessing or the generation of moving meshes. It is particularly advantageous for simulating scenarios involving complex geometries and dynamic processes. Key features include:</p>



<p class="has-black-color has-text-color has-link-color wp-elements-4df790b440acf5007eafc9bc6dc3599f">◆&nbsp;<strong>Continuous Particle Size (CPS):</strong>&nbsp;Enables flexible particle size configurations for enhanced simulation accuracy.</p>



<p class="has-black-color has-text-color has-link-color wp-elements-794b7e83be60ad0d063b3d290fd9590b">◆&nbsp;<strong>Wall Particle Refinement:</strong>&nbsp;Allows detailed resolution near walls for more precise results.</p>



<p class="has-black-color has-text-color has-link-color wp-elements-6661c27ec93b9102d92c13f64b6ef68c">◆&nbsp;<strong>Keyframe-Based Motion Definition:</strong>&nbsp;Facilitates the intuitive setup of motion patterns.</p>



<p class="has-black-color has-text-color has-link-color wp-elements-190606b84a2bfa81ddaef58d20743c28">◆&nbsp;<strong>Post-Processing Sensors:</strong>&nbsp;Analyze forces, liquid distribution, and wet wall locations using embedded sensors.</p>



<p class="has-black-color has-text-color has-link-color wp-elements-fd22a59d5eb8f9d809c804ee4bf25001">◆&nbsp;<strong>Python API (PreonPy):</strong>&nbsp;Boosts modeling and post-processing efficiency with scripting capabilities.</p>



<p class="has-black-color has-text-color has-link-color wp-elements-ff8ffc6eebab03554d896c166f74e082">◆&nbsp;<strong>Realistic Rendering Animations:</strong>&nbsp;Outputs high-quality, realistic animations for better visualization.</p>



<h2 class="wp-block-heading has-black-color has-text-color has-link-color wp-elements-5a81fe2bc43c3446a0a49cb4a2b5e2e6" id="h-avl-nbsp-preonlab的運作方式">AVL&nbsp;<strong>PreonLab的運作方式</strong></h2>



<p class="has-black-color has-text-color has-link-color wp-elements-80d6f0662da49814b3bcf8c5a0fa183e" style="font-size:16px">與傳統的計算 流體動力學 ( CFD ) 不同，PreonLab 的模擬採用無網格技術。這不僅簡化了模型的建立過程，也在模擬牛頓流體和非牛頓流體時提供了快速且高效的處理時間。不論您是進行趨勢分析還是尋求精準的預測，PreonLab 都能滿足需求。</p>



<p class="has-black-color has-text-color has-link-color wp-elements-d3e5cd4afe05ade1434576efda31428e" style="font-size:16px">在軟體開發過程中，易用性一直是特別重要的考量。因此，PreonLab 被設計成讓每位用戶只需稍加培訓便能直覺地應用於日常工作中。</p>



<blockquote class="wp-block-quote is-layout-flow wp-block-quote-is-layout-flow">
<p class="has-black-color has-text-color has-link-color has-medium-font-size wp-elements-3b5b0c1c9a05b38b3119e4dd3ce40384"><em><strong>在不犧牲結果品質的前提下，使開發過程儘可能高效。</strong></em></p>
</blockquote>



<p class="has-black-color has-text-color has-link-color wp-elements-01dd851afe104762070bc5e900aaf4a7"><strong>How PreonLab Works</strong><br>In contrast to classical CFD , the simulations in PreonLab are meshless. This not only simplifies model creation. It gives you short and powerful turnaround times when simulating Newtonian and non-Newtonian fluids. Regardless of whether you want trend analysis or precise predictions.</p>



<p class="has-black-color has-text-color has-link-color wp-elements-41304291e596d87699389421490260ab">Ease of use was and still is particularly important in the development of the software. Thus, it was designed so that every user can use it intuitively in his daily work with a little training.</p>



<p class="has-black-color has-text-color has-link-color wp-elements-6b78a1ebe3fca661fe2cb760ed3bc75b">The goal has always been: to make development as efficient as possible without compromising on the quality of the results.</p>

<p><span style="font-family: arial, helvetica, sans-serif;">經 典 CFD 軟體和 PreonLab 之 間 的 差 異 很 快 就 能 解 釋 清 楚 —— 經典 CFD 軟體 基 於 網格創建 ，而 PreonLab 則 選 擇 了 不 同 的 方 法 ：<strong>平滑粒子流體動力學 （SPH） </strong>是 革 命 性 PREON® 技術 的 基 礎 。 </span></p>
<p><span style="font-family: arial, helvetica, sans-serif;">無需網格，所 有 流體力學 難 題 都 可 以 快 速 且 輕 鬆 地 解 決 。同 時， PreonLab 能 為 您 提 供 可靠的視覺化結果 。</span></p>
<p>&nbsp;</p>
<p><span style="font-family: arial, helvetica, sans-serif; font-size: 20px;"><strong>應 用 領 域 <span style="font-family: arial, helvetica, sans-serif; font-size: 10px;"> <span style="color: #ffffff;">PreonLab 齒輪箱 涉水 雪場景</span></span></strong></span></p>
<ul>
<li><strong><span style="font-family: arial, helvetica, sans-serif;"> 齒輪箱 </span></strong></li>
</ul>
<p><span style="font-family: arial, helvetica, sans-serif;">使用 PreonLab 進行 齒輪箱 的仿真，能夠顯著的縮短開發周期。 極短的仿真建模時間，能夠實現設計方案快速迭代，甚至可以在優化迭代中考慮換熱。</span></p>
<ul>
<li><strong><span style="font-family: arial, helvetica, sans-serif;"> 涉水 </span></strong></li>
</ul>
<p><span style="font-family: arial, helvetica, sans-serif;">不同車速及 涉水 深度條件下，車輛的準確運動規律對於涉水仿真非常的重要。 PreonLab 中的車輛懸架模型，能夠更加準確的考慮涉水過程中的車輛姿態。</span></p>
<ul>
<li><strong><span style="font-family: arial, helvetica, sans-serif;"> 雪場景 </span></strong></li>
</ul>
<p><span style="font-family: arial, helvetica, sans-serif;">PreonLab 能夠模擬各種不同屬性的流體，甚至包括雪。 PreonLab 中獨特的雪求解器，能夠幫助用戶進行各種 雪場景 的求解，解決複雜的問題，例如：輪罩內的積雪。</span></p>
<p>&nbsp;</p>
<p><span style="font-family: arial, helvetica, sans-serif; font-size: 20px;"><strong>為 什 麼 選 擇 PreonLab ？</strong></span></p>
<ul>
<li class="ql-align-center"><span style="font-family: arial, helvetica, sans-serif;"><strong>強大的SPH求解器</strong></span></li>
</ul>
<p><span style="font-family: arial, helvetica, sans-serif;">與常規的基於粒子的求解器相比， PreonLab 可以穩健地處理更大的時間步長，將計算時間減少幾個數量級，並且無需人為去定義求解步長。</span></p>
<ul>
<li class="ql-align-center"><span style="font-family: arial, helvetica, sans-serif;"><strong>後處理</strong></span></li>
</ul>
<p><span style="font-family: arial, helvetica, sans-serif;">PreonLab 配備了強大的內建後處理工具，保障流暢易用的量化結果統計還是高品質的影像渲染。</span></p>
<ul>
<li class="ql-align-center"><span style="font-family: arial, helvetica, sans-serif;"><strong>連續粒子尺寸</strong></span></li>
</ul>
<p><span style="font-family: arial, helvetica, sans-serif;">對於有限體積法來說網格細化並不是一個新主題，這也是加速計算的有效手段 。但對於粒子法軟體來說是一個非常大的挑戰，PreonLab 透過連續粒子尺寸（CPS）技術可以實現高效且穩健的粒子細化及合併，同樣達到加速求解的效果。</span></p>
<p>&nbsp;</p>
<p class="ql-align-center"><span style="font-family: arial, helvetica, sans-serif; font-size: 20px;"><strong>更 重 要 的 是 ？</strong></span></p>
<p><span style="font-family: arial, helvetica, sans-serif;">粒子 也 非 常 適 合 為 其 他 材 料 建模。  PreonLab 可 以 用 彈塑性模型 和 剛體模擬 各 種 類 型 的 雪，當 然 也 是 用 的 隱式解法 。</span></p>
<p>&nbsp;</p>
<p class="ql-align-center"><span style="font-family: arial, helvetica, sans-serif; font-size: 20px;"><strong>新 奇 功 能 ？</strong></span></p>
<p><span style="font-family: arial, helvetica, sans-serif;">上 述 並 不 是 PreonLab 能 做 到 的 全 部 ！ PreonLab 還 有 一 些 其 他 特 異 功 能 可 滿 足 你 一 切 所 想 。</span></p>
<ul>
<li class="ql-align-center"><span style="font-family: arial, helvetica, sans-serif;"><strong>A柱溢流現像模擬</strong></span></li>
</ul>
<p><span style="font-family: arial, helvetica, sans-serif;">雨天行車側窗被雨水覆蓋嚴重影響駕駛透過後視鏡觀察車輛週邊環境，極易引發交通事故。 雖然該現象無法避免，但是我們可以透過模擬分析手段去優化結構設計，進而確保我們後視鏡的可觀察度。 PreonLab可以透過耦合不同工況下的空氣流場進而分析出對應工況下A柱溢流後雨水在側窗的分佈情況，方便我們提升車輛主動安全性能。</span></p>
<ul>
<li class="ql-align-center"><span style="font-family: arial, helvetica, sans-serif;"><strong>泥水污染評估</strong></span></li>
</ul>
<p><span style="font-family: arial, helvetica, sans-serif;">PreonLab可以透過非牛頓流體模擬車輛通過泥水路面後車身以及機艙內關鍵部件的污染情況。 一方面可以引導我們車身擋泥板等外飾件的設計，另一方面也可以提示我們是否要對關鍵部件做一些必要性的擋板以提升部件的使用壽命。</span></p>
<ul>
<li class="ql-align-center"><span style="font-family: arial, helvetica, sans-serif;"><strong>雪屬性資料庫</strong></span></li>
</ul>
<p><span style="font-family: arial, helvetica, sans-serif;">PreonLab可以模擬積雪路面行車和雪天行車等不同雪場景。然而雪的形態和屬性和天氣狀況有很大關係。 PreonLab 以彈塑性模型和剛體模擬各種類型的雪，並且根據工程經驗內建了6種常見雪的屬性參數供使用者直接呼叫。</span></p>
<ul>
<li class="ql-align-center"><span style="font-family: arial, helvetica, sans-serif;"><strong>自動駕駛感應器水管理</strong></span></li>
</ul>
<p><span style="font-family: arial, helvetica, sans-serif;">自動駕駛功能的可靠性直接影響到我們的行車安全，也是我們主機廠研發人員和終端使用者都非常重視的重點。 功能可靠性的前提是我們的雷達或攝影機能夠擯除幹擾因素獲得準確的訊號。 PreonLab可以較全面的輔助我們分析車輛各種水環境下，雷達或攝影機水的覆蓋情況，引導我們進行設計優化以提升功能可靠性。</span></p>
