 Hello,

I am trying to generate this mesh like the picture here: 

However, I used mapped face meshing and since I cannot use inflation I am struggling to make the cell sizes smaller along the edges. This is what I currently have:

I would really appreciate your advice!

Hello njakimovska,

You need to assign Edge Sizing with appropriate biasing to refine the mesh. Check out below video on edge sizing and biasing.

Hi, thank you for your answer. 

I was also wondering how to get refinement at these(the ones market with a red arrow) sections of the nozzle. Because what I have are not straight lines like here.

You may need to slice the face at these locations to get edges. Then you can use those edges to give sizing.

You need to spit the face at those locations (shown by red color in below image) and then assign edge sizing with baising on the vertical edges (shown by yellow color)

Hi thanks for your reply, I split those faces and created the mesh. However,

when I name the outlet of my nozzle I get an error in the setup saying "cannot change surface body to fluid. They are different kinds."

 

Any suggestions on how I can fix this?

You can change it to Fluid in solver.

Hello
Is this error in meshing or in the solver? Could you please post a screenshot?

Thank you.
