[lammps-users] missing kspace_style in current lammps distribution

Dear support,

I have just downloaded the currently available lammps build at the sandia website. I need to use the new (at least, to me) kspace_style ewald/n feature.

The .tar file expands into the lammps-26Apr10 folder. The program compiles well, but unfortunately when running it cannot find the required style for that command. Did I miss something?

Thank you very much in advance.

yes. you have to "install" optional features before compiling a lammps
binary. please check out the documentation more details.

Hi, Steve,

I wonder if this is a new requirement for building the latest version of lammps?
I remember I didn’t use the “make yes-user-ewaldn” command for the old version, and I was able to use “kspace_style pppm 1.0e-5” without any complain.

Thanks a lot.

This is a feature for using an ewald summation for other interactions - like LJ.

PPPM is standard. ewald/n is not - it's in a user package.
