</div></div>Hi Javier,<br>
<br>
Looking at you model my first question is how important is to<br>
model the iron sheet as volume? The ratio sheet thickness to the hole<br>
radius looks small thus the question is if we can neglect the sheet<br>
thickness. I know it can change the flow pattern but on the other<br>
hand it can make the mesh generation easier (for the simulation<br>
the drawback is the presence of internal boundaries).<br>
<br>
