Question of compiling lammps on Desktop

Dear all lammps users,

I have a 2015- May -15 lammps package installed on the desktop(linux), However, I have issue when I was using any command related with lattice boltzmann. For instance, it shows error that fix lb/fluid command not found. It seems the lattice boltzman package is not compiled. I have tried both make serial and make mpi command, but neither works for lb. I’m sure the input file has no error since it runs in supercompurer and I don’t think lb package is an optional package that require additional libraries. I’m not sure why make serial and make mpi not working.

Thank you

Probably because you did not explicitly install the user-lb package? Try make yes-user-lb first and then compile again.
