I'm using symmetry and modeling 1/4 of the object (with the side benefit that we observe the variations where it's most important, no slicing required).<br><br>Anyway, if you observe the screen shot, it appears physically incorrect, namely there is no continuity across the intimate surfaces, that the continuity exists only at Z=0. Now, I did scale this from a 2D example I found on this forum, so it would make sense -- though I'm not able to identify where continuity is limited in the input files.<br><br>Any help would be greatly appreciated.<br><br>Regards,<br>Dan<br></div></body></html>
