Restart with hybrid

Hi
I am using rigid bodies as rings, with constant velocity, surrounding spherical particles and restart it successfully. but I am not so successful in running the model composed of rigid molucular particles interacting with mesh boundaries. In the former case I have used these comments in the restart file:

atom_style granular
newton off
communicate single vel yes

neighbor 0.001 bin
neigh_modify delay 0

read_restart ???

####particles properties
fix m1 all property/global ????

pair_style gran/hertz/history
pair_coeff * *

timestep ????

# define mesh walls
fix bottom all mesh/surface/stress file bottom.stl type 3
....

#####Define groups of particles and walls as it was defined previously
group particles type 1
group nveinteg type 1 3
group rings type 2

##### define groups for rigid bodies as it was defined previously
group r1 id <> 75001 77208
...........

#####Define fix rigid based on groups as it was defined previously
fix rigid rings rigid group 20 r1 r2 r3 r4 r5 r6 r7 r8 r9 r10 &
r11 r12 r13 r14 r15 r16 r17 r18 r19 r20 &
force * off off off torque * off off off

##### integrating
fix integr nveinteg nve/sphere

and the rest

I wish it may help you.
Best wishes
