Isosurface generator

Requirements

• HDF5
• Eigen3
• OpenMP & MPI

Please make sure to set paths for Eigen3 and HDF5 in CMakeLists.txt.

set(EIGEN3_DIR C:/Lib/Eigen-3.4.0-MSVC/share/eigen3/cmake)
set(HDF5_DIR C:/Lib/HDF5-1.10.7-MSVC/cmake/hdf5)

Data Preparation & Settings

1. Create a case dir $CASE_DIR$ and save shonDy's particle results in it (one hdf5 file for each frame).
2. Create a controlData.json in $CASE_DIR$.
3. Set H5_PATH as the file names for all frames, separated by ",".
4. Set NEED_RECORD as true if you need to save the record files while running (otherwise set false).
5. Set P_RADIUS as the particle radius (always make sure it's correct).

Build & Run

1. To build the program, please enter

./Allmake

It is built in release mode by default. If you want to build it in debug mode, please enter

./Allmake debug

2. To run the program, please enter

./Isosurface_smiplify.exe $CASE_DIR$

3. The isosurface mesh results will be exported as obj files to $CASE_DIR$.
4. If you got METIS ERROR, USE DEFAULT SINGLE THREAD during a run, that is because the parallelization modification of Mesh Generate phase has not been completed, you will end up with normal results.
