[ESPResSo] Re: Can not activate LB feature

[g9611559]

Hello Shih-ju,

at the current point, you can use Lattice Boltzmann only with
periodic boundary conditions in all dimensions. The error message
comes from you trying to use it together with constraints, i.e. walls
etc. (#define CONSTRAINTS in myconfig.h). This is not supported at
this time.

Regards,
Kai
