MPM Snow Simulation

Compilation

The following instruction is tested on Ubuntu 18.04 LTS with g++7.5

Dependencies

Install Nova library and OpenGL viewer

The Nova library can be downloaded from GitHub using the following command:

git clone https://github.com/OrionQuest/Nova.git

Example projects that use the Nova core library live in a separate repository, and can be downloaded using the following commands:

cd Nova/Projects
git clone https://github.com/OrionQuest/Nova_Examples.git

Nova depends on several libraries such as GLM,FreeType,GLFW,GLEW,Boost,Assimp, etc. Run the following command to install all the dependencies:

sudo apt-get install libboost1.62-dev libboost-program-options1.62-dev libboost-filesystem1.62-dev libboost-regex1.62-dev libglfw3-dev libglew-dev libglm-dev libassimp-dev libfreetype6-dev

An alternative:

sudo apt-get install libboost-dev libboost-program-options-dev libboost-filesystem-dev libboost-regex-dev libglfw3-dev libglew-dev libglm-dev libassimp-dev libfreetype6-dev

The build system uses cmake (version 3.0 or higher). We recommend the use of the graphical version ccmake for easy configuration of the environment variables. The best way to install the latest version of cmake and ccmake is to first run the following command:

sudo apt-get install cmake
sudo apt-get install cmake-qt-gui
sudo apt-get install libncurses5-dev

Clone Project

Nova/Projects. The partial directory should look like this:

cd Nova/Projects
git clone https://github.com/SoldierDown/Non_Ficks_Diffusion.git non_ficks_diffusion

The directory should look like this:

.
+-- Projects 
|   +-- non_ficks_diffusion
|   +-- Nova_Examples
|   +-- CMakeLists.txt
...

Build

Run the following commands in order:

cd Nova
mkdir build
cd build
ccmake ..

Set CMAKE_BUILD_TYPE to Release, and turn OFF the following flags: ENABLE_OPENIMAGEIO_PLUGIN, ENABLE_SOIL_PLUGIN, ENABLE_VARIATIONAL_FLUIDS, USE_C11_REGEX, USE_DOUBLES.Turn all the other flags ON. Press c to configure, and then g to generate the Makefile. Finally, run the following command:

make -j 8

Configure OpenGL

Run the following commands in order:

cd build/
ln -s ../Projects/Nova_Examples/opengl/example/nova.conf .
ln -s ../Projects/Nova_Examples/opengl/example/fonts/ .
ln -s ../Projects/Nova_Examples/opengl/plugins/Grid/shaders/ .

Choose the correct plugin for visualization in nova.conf in Nova/build/

...
#Plugin=libplugin_Embedded_Deformables
Plugin=libplugin_MPM
...

Here are some of the command options for both plugins.

• ALT-P: planar camera
• P: play-pause
• S: next frame
• SHIFT-S: previous frame
• R: reset frame
• F2: show/hide background grid
• Scroll: zoom in/out
• Left-mouse: rotate
• Right-mouse: translate

Run

Go to the build directory (Nova/build/), run the following command

./bin/mpm_2d -test_number 18 -size 64 64 -threads 8 -last_frame 300

View Result

./bin/opengl mpm_2d_18
