工程師您好，這次我碰上的問題主要和ICFD_BOUNDARY_FSI有關，因為我想要做的是像這種，降落傘是需要他配合流體產生形變的，所以我需要加上FSI流固耦合的keyword。

我有將流體和固體都分別分開做，在LSRUN裡面也都順利的求解成功了，成果如下圖所示:

因此我就想說加入FSI嘗試看看，但是求解卻出錯了，然後以下是他的Error:

我有嘗試過許多方式，如:MAT設定是否有出錯，但後來我參照了網站上的範例

全部keyword和參數也都跟他設置的相同，但是還是一樣會出錯，因此想請教在使用ICFD_BOUNDARY_FSI是有甚麼需要注意的，還是我有哪邊是有遺漏缺失的，再請工程師撥冗回復，謝謝。
