[lammps-users] Substitution for illegal variable

Hello,

I have below error message but I have no idea about it.
The error message occurs only during main run.
I mean, warmup run goes okay with same ensemble (e.g. NVT).
Could anyone help me know why this happen please?

this means that you are trying to reference a variable
that has not been defined. most likely you have a
typo in your input script or the -var argument.
