<div dir="ltr"><div><div>Hello Nek's, <br><br></div> I have a couple of questions regarding the simulations in 2D axisymmetric case.<br> The first one concerns the variational problem. If IFAXIS=T, what Navier Stockes equation is utilized- the one in cartesian coordinate system or the one in cylindrical coordinate system (and what gradient of test function is taken)?<br></div><div> The second one concerns stiffness matrix. It seems to me that we add the suplement term if an element is
placed at the axe (ifrzer(e)=true). Why do we do this? Plus, different derivative matrix are utilized in differents collocation points (Gauss-Lobato-Jacobi) for theses elements but added term isn't utilized with stress-formulation.<br> <br><div>Thanks a lot,<br><font face="Arial"><b><span style="font-size:18px"><span style="color:rgb(0,0,255)"></span></span></b></font></div><div><br></div>ANDREY</div><div><br><table border="0" cellspacing="0"><tbody></tbody></table><table width="1" border="0" cellpadding="0" cellspacing="0" height="15"><tbody><tr><td><br></td><td> <a href="http://www.multitran.ru/c/m.exe?t=553818_1_2&s1=%E2%E0%F0%E8%E0%F6%E8%EE%ED%ED%E0%FF%20%E7%E0%E4%E0%F7%E0" target="_blank"><br></a></td></tr></tbody></table><a name="1518243a4b79f1a6_phrases"></a>
