Hi Hermjan, The best way to specify a gaussian curve as initial condition it is to use a free initial condition and specify the bed level:<div class="lfr-code"><table><tbody><tr><td class="line-numbers">1</td><td class="lines"><div class="line">q=2;</div></td></tr><tr><td class="line-numbers">2</td><td class="lines"><div class="line">sig=150;</div></td></tr><tr><td class="line-numbers">3</td><td class="lines"><div class="line">mu=600;</div></td></tr><tr><td class="line-numbers">4</td><td class="lines"><div class="line">etab_max=2;</div></td></tr><tr><td class="line-numbers">5</td><td class="lines"><div class="line">etaw=4;</div></td></tr></tbody></table></div><div class="lfr-code"><table><tbody><tr><td class="line-numbers">1</td><td class="lines"><div class="line">x=input.grd.dx-input.grd.dx/2:input.grd.dx:input.grd.L-input.grd.dx/2;</div></td></tr><tr><td class="line-numbers">2</td><td class="lines"><div class="line">etab=etab_max*exp(-(x-mu).^2/sig^2);</div></td></tr><tr><td class="line-numbers">3</td><td class="lines"><div class="line">h=etaw-etab;</div></td></tr></tbody></table></div><div class="lfr-code"><table><tbody><tr><td class="line-numbers">1</td><td class="lines"><div class="line">input.ini.initype=2; </div></td></tr><tr><td class="line-numbers">2</td><td class="lines"><div class="line">input.ini.u=q./h; </div></td></tr><tr><td class="line-numbers">3</td><td class="lines"><div class="line">input.ini.h=h; </div></td></tr><tr><td class="line-numbers">4</td><td class="lines"><div class="line">input.ini.etab=etab; </div></td></tr></tbody></table></div>
