[lammps-users] SIN&COS

It seems, that in atom-style variable formula

variable EFx atom ${Field}*sin(v_ksi)

sin does not work as it should and gives 0

When I changed to

variable EFx atom {Field}*cos({Pi}/2.-v_ksi)

everything was OK.

(intel MPI fortran compiler)
variable time equal (step)*{NormalTimestep} variable ksi atom -{k0}*cos({phi})*x-{k0}*sin({phi})*z-{omega}*v_time+{k0}*{r0}

I believe the 17Jan11 patch fixed this?
Please try it out.
