[lammps-users] about fix uniaxial

hi everyone:

when I use fix uniaxial for tensile, it is

fix 1 all uniaxial 10 y 2.0

I think it means the length of y direction expend to 2y. However I found the result isn’t tensile

but compress. why?

regards!

The attached script uses the fix uniaxial command you list
and the box expands by a factor of 2 in y. So I don't see a problem.
