cylinder structured mesh
 

hi .

how can i generate a mesh like this in gambit ??

i dont know how to add nodes to have such a mesh !!
any help or tutorial appreciated .

on your first picture you can see a square at center from disk.
Let assume you only have the disk (2d) the decomposition will be a square and then join corners from square to the circle (you need to split the circle with some points)

hi max . thanks for yoyr help . i did it .

hi
I have the same problem. please, if you get any solution tell me.

hi zeinab . while in gambit draw a cylinder then split it into 4 equal parts , make a cube at center of cylinder ,
subtract cube from the cylindrical parts
now use volume mesh >>hex/map

remember to connect the faces .

u can do this in 2d or 3d

Hi Masood, thank you for your help
I working as you tell me, finally i get a five meshed domains, when I wont to export the mesh to FLUENT , must unite all the volumes to be one cylindrical volume to specify the regions, inlet, outlet, etc.
when I do this step the mesh deleted.
what can I do

No need to unite them. Go to boundary condition panel and select all five faces on one side as inlet and corresponding five faces at other side as outlet. Similarly for the outer wall of the cylinder

please see the picture and help me

i need the steps to make a mesh like in pic by gambit . please i need help

Hello All,

I want to do analysis of heat transfer from water flowing through pipes submerged inside concrete. I am modelling in GAMBIT and wish to analyse it on Ansys FLUENT.

Can anybody help me out, how to model and simulate?

Does any tutorials exist?

Hi
I made this mesh on 2d circle, but when I change it to 3d mesh I have negative volume . how can I make it better not to have negative volume? and why I have them?
