In this post, I’d like to talk a bit about how Nek treats the connectivity and therefore periodicity. Despise that we are going into Nek’s structure, the general concept can be applied to other ...

簡介 Nek5000 1 是一個開源的軟體，用來跑流體動力學的模擬， 包含不可壓縮流體(incompressible Navior-Stokes)、和熱傳導的耦合、紊流模型、低馬赫數可壓縮流體的近似解、磁流體等。 主要的特點如下： 開源：就是不用錢，程式碼公開，有錯大家抓。 使用『譜元素法』2，能在相同的計算資源下達到較高的精度。數值格式誤差的低耗散性相對提昇了對紊流的解析...

Hello World! This has been my new year resolution for too long. At last, in 2023, my personal website is online! Welcome! TL;DR Building website is always one of my hobbies. It had occupied my...
