Dear friends;
I want to compute surface of energy so I used loop on the loop, but I get an error as follow :
fix        1 all nvt temp 300 300 0.1
variable srate equal 1.0e10
variable srate1 equal "v_srate / 1.0e12"

variable a loop 20
label loop

fix        2 all deform 1 x erate ${srate1} units box remap x
fix        2 all deform 1 x erate 0.01 units box remap x

variable b loop 20
label loop

fix        3 all deform 1 y erate ${srate1} units box remap x
fix        3 all deform 1 y erate 0.01 units box remap x
run 1
ERROR: More than one fix deform (../fix_deform.cpp:406)
Last command: run 1

Do you have any idea?

Sincerely;
Nili
