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) Sans titre.jpg

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 |

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

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? |
