FAQ

When I change the model file (usually multi Granular Computing), I have encountered the problem of core dump many times. Later, I tried to calculate the example you gave: PeriDEM/examples/PeriDEM/compressive_test/n500_circ_hex/run2/inp. The same problem was encountered.

After the previous calculation was interrupted, I used the results of the previous calculation as the input file and then calculated, but now this method doesn't work because the results of one file haven't come out and an error is reported

Actual Behavior

...

1. The following three screenshots are the problems after modifying the geometric model
   
   
   
   ...

2. The following three screenshots are the run2 file of the compression example given without modifying the geometric model
   
   
   

Steps to Reproduce the Problem

... Please be as specific as possible while describing how to reproduce your problem.

1. cd /PeriDEM/examples/PeriDEM/compressive_test/n500_circ_hex/init_configand sudo sh ./run.sh
2. cd /PeriDEM/examples/PeriDEM/compressive_test/n500_circ_hex/run1 and sudo sh ./run.sh
3. Copy the last result file calculated in step 2 to the "run2 / inp" file path and cd /PeriDEM/examples/PeriDEM/compressive_test/n500_circ_hex/run2 andsudo sh ./run.sh

@yuantangjin pointed out the bug when applying damping between particle and wall

Sharing the conversation with Tangjin with regard to compiling dependencies HPX and PCL for PeriDEM. Hope this will be of some help.

Hi,

If you are using Ubuntu18.04, you should

1. first install the dependencies using apt-get:

sudo apt-get install libboost-dev libvtk7-dev libyaml-cpp-dev libhwloc-dev libjemalloc-dev libflann-dev

2. install HPX and PCL libraries by running the bash script 'install_libs.sh' as follows

cd <peridem-libs-dir> # <-- create a directory where you want to store the HPX, PCL libraries
./install_libs.sh Release # <--- copy install_libs.sh from here https://github.com/prashjha/PeriDEM/blob/main/tools/script/build_scripts/ubuntu-18.04/install_libs.sh and run it

Above will install HPX and PCL.

HPX will be installed to directory /local/hpx/1.3.0/Release

PCL will be installed to directory /local/pcl/1.11.1/Release

3. Now you can install PeriDEM

cd <peridem-dir>
git clone https://github.com/prashjha/PeriDEM.git
cd PeriDEM
mkdir build && cd build

# run cmake
cmake   -DHPX_DIR="<hpx directory>/lib/cmake/HPX" \
        -DPCL_DIR="<pcl directory>" \
        -DEnable_Documentation=ON \
        -DEnable_Tests=ON \
        -DCMAKE_BUILD_TYPE=Release \
        ./..

# make
make -j 4

# run tests
ctest --verbose

I will update the instructions in https://github.com/prashjha/PeriDEM/blob/main/README.md in next few days. Let me know if you have any issues.

Dr Prashjha hello, I am a graduate student from China agricultural university，YUAN Tangjin, I focus on making to you about the near field dynamics and the coupling of the discrete element code, I want to try to run, but ran into trouble when the build environment, want to ask you, in your code “/PeriDEM/tree/main/tools/script/build_scripts/ubuntu 18.04” path, files can be directly used to build the application environment? Or do you want to download the source code of those dependent libraries from the Internet and compile it yourself ? Can you give us some guidance? If I can get your guidance, sincerely thank you !

Hello,

after running install_base/libs.sh successfully, install_peridem.sh failed with error message as follows:

Any suggestion?
