Dear Friends
I want to calculate g vaiaable in a loop but when I use loop my program is aborted,
variable j loop 2
label loopFF
variable PN equal c_Pslab${j}[1]
variable PT equal (c_Pslab${j}[2]^2+c_Pslab${j}[3]^2)^0.5
variable PNPT equal {PN}-{PT}
variable g equal {g}+{PNPT}*${dx}
next j
jump in.input loopFF
Therefore I must use the following script. Is there any way to use loop without any problem?
variable PN equal c_Pslab1[1]+c_Pslab2[1]
variable PT equal (c_Pslab1[2]^2+c_Pslab1[3]^2)^0.5+(c_Pslab2[2]^2+c_Pslab2[3]^2)^0.5
variable PNPT equal {PN}-{PT}
variable g equal {g}+{PNPT}*dx
Thanks
Saly
why does it abort - does LAMMPS give an error message?

Aborted
Can you post a small, simple input script (and data file if needed)
that generates that error? How many processors is it running on?
Steve
Your input script showed up a memory bug with variables, introduced
by the 7Oct10 patch. Try the 17Oct10 patch/version and see if
your problem goes away ...
Thanks,
Steve
