I tried several methods but i am always getting errors. <br />The last error was "floating point error"<br /><br /><br />do u know how to solve this error?<br /><br />if u you dont know, tab could you write the steps that i need to do in gambit and fluent. i will compare it to the steps im using.<br /><br />Waiting for your reply,<br /><br />Thanks ^_^braheemhttps://www.blogger.com/profile/11853077456450509072noreply@blogger.comtag:blogger.com,1999:blog-8385614935184816985.post-66259101959428501472009-01-28T08:20:00.000-07:002009-01-28T08:20:00.000-07:00Hi Rajavel,Thank you for your comment.

Thank you for your comment. <BR/><BR/>There's a fundamental difference between the symmetry and axis boundary conditions.<BR/><BR/>A symmetry BC is used when you have mirror symmetry (could be 2D, or 3D). At a symmetry plane (or line) the normal velocity component is zero, as well as the normal gradients of all variables.<BR/><BR/>An axis BC is used with axisymmetric simulations only so your model should be 2D (in that case, there are no variations in the tangential direction).<BR/><BR/>You can refer to sections 6.14 and 6.16 of the fluent documentation.<BR/><BR/>In your model, assuming it is axisymmteric, you have to change the symmetry BC to axis and use the axisymmetric solver.<BR/><BR/>I hope that was helpful.yNothttps://www.blogger.com/profile/14726971650187585982noreply@blogger.comtag:blogger.com,1999:blog-8385614935184816985.post-54293728262204587112008-10-22T14:12:00.000-06:002008-10-22T14:12:00.000-06:00I am trying to write a guide of definitions of the...I am trying to write a guide of definitions of the boundary condition types in Gambit due to the utter lack of such documentation available. Could you possibly provide more insight into how "axis" and "symmetry" boundary conditions differ? In my particular model, I have used a symmetry condition for my axisymmetric model, but am not running an axisymmetric solver in Fluent. Any information you have would be great!
