2D vortex-induced vibration (VIV) numerical simulations for Re=90, Re=180

Numerical simulation datasets used for non-intrusive reduced-order modelling for VIV problems, via sparse FOM inference (see https://arxiv.org/abs/2302.09981). The corresponding code is available via https://github.com/lgkimisis/VIV_sFOM_POD_inference. Snapshot data from the numerical simulation of two testcases are included, on the VIV dynamics for Re=90 and Re=180 flow over an elipse-shaped, non-deformable solid. The numerical simulation was performed via the Gascoigne3D open-source, monolithic FSI solver (https://doi.org/10.5281/zenodo.5574968).本数据集为基于稀疏全阶模型(Full Order Model, FOM)推理的涡激振动(Vortex-Induced Vibration, VIV)问题非侵入式降阶建模所用的数值模拟数据集，相关研究详见论文https://arxiv.org/abs/2302.09981。配套代码可通过https://github.com/lgkimisis/VIV_sFOM_POD_inference获取。 数据集包含两个测试案例的数值模拟快照数据，对应雷诺数(Reynolds number, Re)分别为90和180的流体绕椭圆形不可变形固体的涡激振动动力学场景。 本次数值模拟采用开源整体式流固耦合(Fluid-Structure Interaction, FSI)求解器Gascoigne3D完成，其关联DOI链接为https://doi.org/10.5281/zenodo.5574968。
