HFSS setup for parametric sweep

Hello, does anyone know how to setup parametric sweep in HFSS for 2 variable at the same time, for example, sweep variable "a" from "0~1" and "b=0.1a" simultaneously.

Thanks.

I do not think you need two parametric setup since
one will uodate the other one. But, when you do the
report you can have two varaibles a and b in it.
