Fluid Simulation:Compile Position Based Dynamics

PositionBasedDynamics is a library for the physically-based simulation of rigid bodies, deformable solids and fluids.

Update 2021

compile GPU version (CMakeLists.txt will find cuda, display ${CUDA_VERSION} to verify if is getting the right version).

See https://melhorum.blogspot.com/2021/03/cuda-8-on-linux18.html to install CUDA and requeriments.

on DualSPHysics/src/source

mkdir build

cd build

export CC=/usr/bin/gcc-5;CXX=/usr/bin/g++-5 #for cuda 8


export CC=/usr/bin/gcc-6;CXX=/usr/bin/g++-6 #for cuda 9

cmake ..

make In some cases you need to reduce cuda version to execute simulation. in case of GeForce GTX 460(with Driver Version: 390.59). I was forced to change from cuda9(supported) to cuda8(supported too) to execute simulations with around 360k particles.
