Hi,

Whats the specs are you giving for creation of infinite sphere. Use default settings. and then try.

hi habeebhabz,
i chose infinite sphere in far field set up, is this what you mean? I havnt changed any settings
thanks

you need to change the infinite spear set up so that it read 360 in for both phi and theta. default is 180 for phi.
