Hi all,<br><br>I am getting these few errors at my upper boundary. Among other things, I have tried using the new damping option, diff_opt =2, because I am using running towards an LES in my inner domain. A solution seems easy but so far my attempts have not yielded success. below is my namelist.<br>
