Regarding this topic, https://www.edaboard.com/threads/111298/, anybody can tell me if is it possible modify the current value? I can not change the original value 1A in the properties!!!
The current value is not set in the source properties, but rather in the source excitations. Right click on "Field Overlays" in the left hand menu and select 'Edit Sources..". You should be able to set the value there.
