[ESPResSo-users] Virtual sites + copy_particles

[Aleksei Kabedev]

Dear all,

I have an issue with "copy_particles" function, while using virtual sites. Actually, I had just compiled it with VIRTUAL_SITES_RELATIVE and it crashed every time after copying any particle, saying

"unknown particle parameter "body_frame_velocity"
    while executing
part 20 pos 0.0 1.0 1.5 type 5 mass 1.0 v 0.0 0.0 0.0 f 0.0 0.0 0.0 quat 1.0 0.0 0.0 0.0 omega_lab 0.0 0.0 0.0 omega_body 0.0 0.0 0.0 torque_lab 0.0 0..."
    ("eval" body line 1)
    invoked from within
"eval part $newid $partcmd"
    (procedure "copy_particles" line 65)
    invoked from within
"copy_particles range 0 $mp shift [expr $sx*1.0] [expr $sy*1.0] 0.0"

I just assume that the problem is either with the copy_particle itself or with the combination of features compiled.

This is the list I use

#define PARTIAL_PERIODIC
#define EXTERNAL_FORCES
#define CONSTRAINTS
#define MASS
#define EXCLUSIONS
#define VIRTUAL_SITES_RELATIVE
#define LB_GPU
#define LB_BOUNDARIES_GPU
#define LENNARD_JONES
#define LENNARD_JONES_GENERIC
#define SOFT_SPHERE
#define HAT
#define BOND_ANGLE

If someone could give me a tip how to fix it, that would be greatly appreciated.

Thanks!
