Reply To: Frozen field simulation not solving for the scalar tracer [CFX]

[Mark Owens]

Hi, that still works for me with a constant source. Try setting a constant source. If that works then it must be that 

step((t-1[s])/(-1)[s])

is evaluating to zero for the time you are running. Try creating an expression for it such as

tracerOn = step((t-1[s])/(-1)[s])

and plotting it in the expression editor. Also, please note that your tracer run will only start at t=0 if you turn off the option to continue the history when restarting
