Title: A hybrid semi-analytical and nite element parametric model to predict flood gate vibrations
Corresponding author: O.C. Tieleman, o.c.tieleman@tudelft.nl

Code language: MATLAB .m-files linked to the SCIA software package

Description:
This model predict the dynamic behaviour of a gate immersed in fluid based on a coupled modal substructuring method. The gate is modelled as a plate with stiffeners and described parametrically. SCIA is used to predict the in vacuo modes and resonance frequencies of the gate. These modes are then used to predict the dynamic behaviour of the gate immersed in fluid with the semi-analytical fluid-structure interaction model in MATLAB. For an extensive description of the model and the main parameters, please see the paper "A hybrid semi-analytical and finite element parametric model to predict flood gate vibrations" (to be published, 2024).

Folder structure
../Case/ - Contains the files specific to the case and the main file which runs the model: case_variablegate.m. Copies of this folder may be made to create other study cases.
../Case/SCIALink - Contains the SCIA model of the in vacuo ate and the files to link it to MATLAB.
../Case/Results - Where the results and figures of the model calculations are saved by default.
../Case/Modes - Where the generated in vacuo model shapes and frequencies of the plate are saved for repeated calculations.
../Model/ - Contains the core files for the fluid-structure interaction calculations.

Files
case_main.m - main file that sets the model parameters, runs the model, and then retrieves and visualizes results.
model_main.m - solves the analytical system of the equations numerically to obtain the response of the plate
model_fluidmodes_... - multiple files that obtain the fluid modal shapes, with or without surface waves or for the overhang section
data... - multiple files that adjust the wave impact data to be used in the model (changing time steps, fitting to the gate surface grid, etc.)
