Hello guys!

first of all, sorry for my bad english

i have to mesh a 2D geometry (attachement) 2d geometry.png

air flows into the chamber and should pass the dashed lines to flow out. The dashed lines are closed in the geometry. In fluent i will appropriate the boundary condition (interior) to them, so the air can flow throuh.

my problem ist that i should create 3 regions (attachement). So i created three surfaces and meshed them. The result was rubish (attachement) mesh.PNG the nodes of regions 1 to 3 are not overlapping. They should overlapping or?

This is my first 2D surface mesh. how can i get overlapping of the nodes.

In 3D geometries i used fluid points. Should i used fluid points in 2D geometries ,too?

Are there other possibilities to create 3 fluid regions? How can i mesh them?

Thank you for your efforts!
