Solution of the acoustic wave equation in 3D using finite difference method.

Equation

$$\frac{\partial^2u}{\partial x^2} + \frac{\partial^2u}{\partial y^2} + \frac{\partial^2u}{\partial z^2} = \frac{1}{c^2} \cdot \frac{\partial^2u}{\partial t^2}$$

where
$u = u(x,y,z,t)$ - displacement vector (or acoustic pressure)
$c$ - speed of sound

This program runs on GPU. So, the nvcc compiler is used.

compile it with

nvcc main_proj.cu -o main_proj

and run wih

./main_proj

Result

This program outputs .vtk file that can be opened in ParaView.
