My name is Zhipeng Yu, and I am a PhD student of Tsinghua University, China. Recently, I encountered some problems when I used Nektar++ to carry out simulations of a flexible cylinder. The problems are shown as follows: 1. Can we define the natural frequency of a flexible cylinder in the in.xml file? Besides, could you tell me the relationship between EI and fn? It seems the definition of some parameters is different from other references, such as the mass ratio. 2. During post-processing, the real displacement of a cylinder cannot be seen by using "FieldConvert in.xml in.fld out.dat". Are there any ways to show the transformed coordinates of the cylinder in tecplot? 3. How to turn the DNS to LES by Nektar++? Thank you for your patient. Best regards. Zhipeng Yu
HI Zhipeng, Can I direct you to Mohsen (cc’ed) who I think might be best able to answer you questions. Cheers, Spencer.
