Acoustic Vibration of a Fluid in a Three-Dimensional Cavity: Finite Element Method Simulation using CUDA and MATLAB
An implementation of a FEM acoustic model on a GPU using C/C++ and CUDA libraries.
For CUDA, just do make:
cd CUDA
make
./fem_solver A B C
A: Number of nodes n in grid n x n x n
B: Method type. 0 for Conquer and Divide, 1 for Jacobi.
C: Precision type. 0 for Single, 1 for Double.
For MATLAB, run: fem_acoustic_1.h.
Arbitrary eigenvectors were used to graph the sound pressure distribution for low and high frequencies in the cavity and they are shown bellow:
CUDA 9.2 is needed(also cuSolver).
NVIDIA Titan X, Tesla P100 and Tesla V100 were tested.
