Sorry, I made a mistake since I gave same physical surface id twice and it was not saving th second set of surfaces. The orientation change works correctly if I give different ids.<div><br></div><div>praveen<br><br><div class="gmail_quote">

Hello<div>I want to have same surface orientation for all surfaces in a 2-d mesh. I follow the manual and use negative surface numbers in the "Physical Surface" part. But this does not seem to make any difference. I have attached example. Try with all positive and negative ids at the bottom of file. It gives same mesh as checked by doing diff. Is this supposed to work ?</div>
