Who can help me check my variable definition ? I really cannot find out where I am wrong. My lammps vision is LAMMPS (31 Aug 2011)…

input script
…
# variable definition
variable wall_wid equal (2+${epsl})a # wall width 3 slices atoms for bcc<br>variable vz equal {vp}
variable end_retain equal 10a # increase when vp and steps increased!<br>variable EFiniy equal {wall_wid}+{end_retain}<br>variable EFleny euqal {leny}-${end_retain}



output
…
variable end_retain equal 10*a # increase when vp and steps increased!<br>variable end_retain equal 10*2.8606 variable EFiniy equal {wall_wid}+{end_retain}<br>variable EFiniy equal 5.7240606+{end_retain}
variable EFiniy equal 5.7240606+28.606
variable EFleny euqal {leny}-{end_retain}
variable EFleny euqal 343.272-${end_retain}
variable EFleny euqal 343.272-28.606
ERROR: Illegal variable command

There is a typo: you wrote euqal instead of equal.

yeah,… These spelling mistakes are often hard to check out. Are there any good methods to avoid it???

Thank you very much!

using an editor with properly programmed syntax highlighting helps.
