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 __________________ In memory of my friend Hervé: CFD engineer & freerider

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

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

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?
