It contains multiple integrators that you may switch and compare through changing the integration_scheme variable in the code. Its value can be one of the following:
IT_PIC: original particle-in-cell (PIC)
IT_FLIP: original fluid-implicit-particle (FLIP)
IT_RPIC: rotational particle-in-cell (RPIC)
IT_APIC: affine particle-in-cell (APIC)
IT_AFLIP: affine fluid-implicit-particle (AFLIP)
IT_ASFLIP: affine separable fluid-implicit-particle (ASFLIP)
It also supports using different orders for velocity evaluation, where one may change the velocity_order variable in the code. Its value can be one of the following:
VO_EULER: first order evaluation
VO_RA2: Ralston's second order evaluation
VO_RK3: Runge Kutta's 3rd-order method
VO_RK4: Runge Kutta's 4rd-order method
APIC2D depends on the Eigen libraries (included) as well as GLUT for simple visualization.
To compile APIC2D, you'll need CMake on Mac OS X or Linux, or CMake-GUI (https://cmake.org) on Windows.
On Mac OS X or Linux:
- make a directory, say, build, with mkdir build, enter the build directory, type cmake ..
- Optionally you can adjust the options with ccmake .
- type make to compile the code. For speeding up the compilation process you may use make -j.
On Windows:
- open CMake-GUI, enter the correct directory for source code and build. Then click Configure, choose your installed version of the Microsoft Visual Studio.
- after configuration you may find several libraries not found, check the Advanced box and locate those missing libraries manually. Please make sure you have picked the libraries corresponding to the architecture you have selected (say, 32-bit libraries for x86, and 64-bit libraries for x64).
- click generate after fixing all missing variables to generate your Visual Studio solution.
- open the solution and compile the code.
编译过程 需要freeglut x86版本支持，所以先用vs2019 x86编译了freeglut，然后相应加入头文件和库文件，运行dll
