<p>Hello Everyone,</p>
<p> I am a brand new user of Nek5000. I started off with the periodic hill tutorial. In the mesh modification section, the expression y'(x,y) = y + (3-y)(A + A\tanh(|x-B|-C)) where A,B,C are 0.166,4.5 and 3.5</p>
<p>respectively is yielding y' ~ 0.88 for x,y = 0. But, as far as i think as the hill height is chosen to be 1, the expression should yield a value (y') >=1 for x=0 and all 0<=y<=3. Kindly, help me regarding this.</p>
<p> </p>
