who can help me in drawing this mesh-please reply
 
hey I sent a previous request in drawing a symetrical pipe with two inlets like that shown on the file http://www.quickfiles.net/860919 but I still not get any answers about so is there anybody can assist me with it by sending me a journal file?

thanks for your reply Andrea

I cant even make out what your saying with that figure. It appears to be some meshed face. Im expecting to see a half pipe geometry in which case something can be built and a journal returned.

Yes you are true its for a face I just took it from a paper I want work it now in fluent hence I need to draw a 3D cylinder (pipe) with inlet divided into two parts like that shown on the figure because there is two fluids flowing with different velocities , the cylinder is symmetric along the vertical direction (cannot be symmetric along the x-axis because there is two fluids-stratified flow). I hope this gives clear idea now.

Well this is basic stuff for geometry creation in gambit. You need to create a primitive cylinder then split by face or volume then use quad map surface meshing to get something similar to that in the picture. I recommend you supply a 3d image of the geometry only you need meshing or supply the CAD itself then a jou or dbs can be returned.

thanks red for the reply. The problem with this mesh the inlets not lying on the middle of the pipe cross section because they not equal in areas so its difficult to split? can you tell me what you mean with CAD and how the jou file can be returned from supplying 3D image?

well ok. you draw the 3d model either in CAD (such as ProE or CATIA for example) then send that with fluid regions split up. We can then return a journal that meshes it to follow your image.

hey red, I am really not know this procedure and I have no experience with these codes I used gambit only for drawing geometries so if you can assist me by drawing the mesh for me this will be kind from you.
