set diameter of particle: "Group ID in varibale formula does not exist"

Hello everybody,

I am struggling with the mentioned error for some time now and I cannot find the reason of this error.

I'd like to increase the diameter of my particles (2d-problem) within a certain period of time with the following commands:

variable dia equal ramp(0.1,0.1005)

region reg block -5 5 0 1 0.005 units box

run 50000 every 1000 "set region reg diameter ${dia}"

Can anybody help me? I already tried to use a group command to set the diameter of the particles belonging to this group within region reg - same error...

Thanks in advance
kind regards

Sebastian

The only error I get with those 3 commands added
to bench/in.lj is Illegal region command, which
makes sense b/c you have 5 numeric params instead
of 6.
