I am using the 'awgn' function for the initial random seed values for velocities in the channel likewise: <FUNCTION NAME="InitialConditions"> <E VAR="u" VALUE="awgn(0.01)" /> <E VAR="v" VALUE="awgn(0.01)" /> <E VAR="p" VALUE="0" /> </FUNCTION> I require the Initial Conditions (as shown above) to be symmetric with respect to channel centerline. Is there a way to achieve the same? Thanks and Regards Nandan Sarkar Research Scholar Department of Mechanical Engineering Indian Institute of Technology Kharagpur
