<P>1. Set Solver type to GENERIC</P>
<P> </P>
<P>2. When Meshing, make sure the edge node count is 3 (for midpoints). This should make the face count 8 and the volume count 20 nodes. </P>
<P> This setting is necessary to take advantage of Nektons mid side node support.</P>
<P> </P>
<P>3. Use the zones to label faces as Boundary conditions. Select multiple faces if you like. Since the solver is set to generic, just call the BC</P>
<P>anything you like, "Inlet" for example. The Matlab code will ask you "What did you mean by Inlet", where you would input 'v' for a fortran </P>
<P>velocity input. If it is a thermal problem (TBC = 1 in the inputs in rea_write), it will ask for the momentum and thermal BC. In gambit, any</P>
<P>face that is not labeled with a BC type is assumed to be a Wall. </P>
<P> </P>
<P><STRONG>NOTE: The Mesh must be HEX & Edge node count 3!... ONLY works for 3D cases!</STRONG></P>

Alternatively you could set the face from 4 to<BR>> 8 or the volume from 8 to 20 nodes. The extra nodes that gambit throws<BR>> because of this are the midpoints. For Nekton, the recent midside<BR>> node support feature which fits a parabola through the two corner<BR>> points and midpoint of the element side is where this comes into<BR>> play. <BR>> <BR>> <BR>> <BR>> So all you need to do is make sure you have set the mesh nodes as<BR>> above, and the matlab code does the rest. It separates the element's<BR>> corner nodes from the midpoint nodes. The midpoint nodes are written<BR>> into the curved side section of the the REA, whereas the corner points<BR>> are written into the Mesh data section. So...The matlab code only uses<BR>> the flag 'm' for curved side data. <BR>> <BR>> <BR>> <BR>> Also, in the inputs section you can specify a maximum radius for<BR>> consideration. The code will check each edge's corner and midpoints<BR>> and determine the radius curvature. If it is too large it considers it<BR>> a straight edge and moves on.<BR>> <BR>> <BR>> <BR>> Hope this helps,<BR>> <BR>> <BR>> <BR>> Michael<BR>> <BR>> <BR>> ----- Original Message -----<BR>> From: nek5000-users@lists.mcs.anl.gov<BR>> To: nek5000-users@lists.mcs.anl.gov<BR>> Sent: Friday, June 4, 2010 6:24:06 PM GMT -06:00 US/Canada Central<BR>> Subject: Re: [Nek5000-users] to Michael--> Nek5000 & Gambit, blocked<BR>> file<BR>> <BR>> Hi Michael,<BR>> <BR>> Thanks very much for the code.
