Mesh Swept Problem

Dear All,
I need to reduce the elements of the mesh in the fluid domain.
At the beginning I used a tetrahedral mesh but it is too dense in the axial direction, while I need it mainly in radial direction.
For this reason I'm trying to create a triangular mesh on the boundary of the domain 2 and sweep it in the axial direction. (Attached 1.png)
The source and the destination faces are not the same, how can I build a lighter mesh in this domain (2.png) ?
Thank you in advance for your support!

Hi
try to mesh the central boundary at 150 mm, then copy that mesh to both ends, then sweep forwards, later sweep (separate node) backwards
Main restriction (modify your model accordingly by adding internal boundaries) have the same (at least similar) topologies at source and destination boundaries

Good luck

Hi Ivar,
thank you for your reply.
I reduce the mesh elements in z direction editing the scale factor in "Free Tetrahedrical -> Scale Geometry".
I reduce it to 0.1 from 1, in this way mesh elements decrease about 10 times. (I add a screenshot)
Thank you again for your help,
have a nice week.
