ERROR: Label wasn't found in input script

Submitted by laudari on Fri, 01/22/2021 - 06:37

Hello Liggghts forum,
I tried to save some variables in csv format which are mentioned below.
While running simulation,
I got an error.
I think I did mistake while including ' jump command and label'

Could you kindly help me to solve this problem?

Thank you so much

My script
============================\
################################################################################################################
compute 1 all erotate/sphere
thermo_style custom step atoms ke c_1 vol
thermo 1000
thermo_modify lost ignore norm no
compute_modify thermo_temp dynamic yes

variable t equal step*dt
#variable sm equal sim_time
variable a equal atoms
variable b equal fz
variable c equal fx
variable d equal fy
variable f equal vx
variable g equal vy
variable h equal vz
##########################################################################################################################
run 100
#########################################################################################################################

fix file all print 1 "$t, $b,$c, $d, $f, $g $h, $a " file test.csv title "time, fz, fx, fy, vx, vy, vz, a"
=================================================
jump in.particleA runloop
jump SELF runloop
label break
run 1000000 upto
unfix ins

======================

It would be a great help if I get some solutions to this problem.

Hello
You have not defined any label for runloop in the script. Also, I am not able to understand why you to use jump runloop . If you still want to use, you can define:

label runloop
%%%% Commands%%
jump SELF runloop
label break
run 1000000 upto
unfix ins

Hello Shubham, really appreciate your reply.
I was having problem in loop commands. Since I am new in liggghts, I am trying to give my full effort.

DId you mean by I have to define label like this:

label runloop

variable b loop 5
variable c loop 5

jump SELF runloop
label break
run 1000000 upto
unfix ins

Thanks alot.

Hello
The problem with the above algo is that there is no condition to exit the loop. You can consider the following example and try to modify your code:

label loop
variable a loop 5
print "A = $a"
if "$a > 2" then "jump in.script break" ## Condition to break the loop
next a ## to increase the value of variable a
jump in.script loop ## To jump again to the first label
label break ## Break label (once you jump to this step, loop is terminated!!)
variable a delete

Let me know if you have further questions

Cheers
Shubham

Hi @Shubham really thank you for your reply,
And sorry for late response.
I will be back if I get any problem while including loop idea in my script.

Thanks a lot
