error while loading shared libraries: libiomp5.so

This implies that the system could not find the shared object file required by the nextnano executable. Please specify the path to this file by setting the variable LD_LIBRARY_PATH:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/path/to/file

Please see Running nextnano++ & nextnano³ on Linux from Terminal for details.
