Hi,

a simple testcase with the current master:

setmd box_l 32 32 32
setmd skin 0.0
setmd time_step 0.01
thermostat off
lbfluid cpu agrid 1.0 dens 1.0 visc 1.0 tau [setmd time_step]
constraint rhomboid corner 0.1 0 0 a 10 0 3  b 0 10 0  c 0 0 10
direction 1 type 0
integrate 0

works fine. Please send a minimal script that fails, plus your
myconfig.hpp. That could help understanding where the problem is.

Kind Regards,

Marcello
