hello everyone
I met a problem when trying to add package molecule, a similar thread was post last year but with no answers, as below:
i am very new to this software and also very new in the field of particle simulation. I am planing to do the Nanoindentation simulation through LIGGGHTS. Therefore i need to create a bond model, which is only possible through the MOLECULE package.
I have tried to install this package but it is showing some error. I have tried to do it in two steps, as mentioned in LIGGGHTS online document.
Step 1: type make yes-molecule (from src directory)
Terminal gave back the following statement:
Installing package molecule (which makes me feel happy :))
Step 2: make g++
Terminal gave back the following statement:
make[1]: Entering directory '/home/braj/LIGGGHTS-PUBLIC/src/Obj_g++'
g++ -g -O -DLAMMPS_GZIP -DLAMMPS_JPEG -I../../lib/poems -I -DMPICH_SKIP_MPICXX -DFFT_FFTW -I/usr/local/include/voro++ -c ../image.cpp
../image.cpp:50:17: fatal error: mpi.h: No such file or directory
compilation terminated.
Makefile:100: recipe for target 'image.o' failed
make[1]: *** [image.o] Error 1
make[1]: Leaving directory '/home/braj/LIGGGHTS-PUBLIC/src/Obj_g++'
Makefile:72: recipe for target 'g++' failed
make: *** [g++] Error 2
I will be very thankful if someone can help me out with this problem.
