Need help for Mesh Refinement

Post by Sultana_19 » Wed Jun 09, 2021 3:19 pm

Dear all,

I am trying to refine the mesh around the two arcs in my model domain so that the shape of this two arc is visible after creating the mesh.I tried to refine the mesh using point option but it gives me an error.Without mesh refinement when I generate the mesh the shape around the arc is triangular which I would like to avoid. I was also looking at the uploaded example of Siyal for pitcher irrigation and I wanted to do something similar but could not solve the problem. Any insight in this matter will be really helpful. I have also attached the model.

Kind regards,
Sultana

This is really simple - see attached figure

Hi Mirek,
Thank you very much for your quick response. I can create the mesh after deleting the second curve. But I also need this curve for other steps in my simulation. I wanted to have the mesh thickness equal to the distance of these two arcs which is 0.5 cm. In that case I can specify the finite element size as 0.5 cm right?

But can I generate the mesh without deleting this curve in my model like the one which was done in siyal model example? I have attached the picture of siyal model here for your reference.

Of course, you can use two curves, you only need to use a suitable mesh refinement on them (or at their definition points). I also recommend using two surfaces - see attached picture.

Thank you very much Mirek! It worked out perfectly.
