Hi Ritta,
what you need is an outline that is sampled to fit exactly the density of the mesh you want to make.
The problem in Blue Kenue, as you noticed yourself, is that it will first resample the outline and then create the mesh and sometimes the resampled outline points don't fit very well with the density you want in your mesh.
So what you need to do to solve this is to generate a better sampled outline. One way to do this, is to generate the mesh that you wanted to make, but extend your boundaries, i.e. your outline, a little bit further. So you make a slightly bigger mesh and you can use this mesh to resample your outline because it will have the density that you want in your final mesh.
So the steps to get there are:
1. set up your mesh generating like you already did.
2. replace your outline with an outline that is a little bigger (an outline that makes your domain a little bigger so that you create a bigger mesh)
3. generate the bigger mesh
4. add a new mesh generator
5. add your first outline as an outline
6. add the bigger mesh as the density file (to use this mesh as a density parameter you have to dubble click on it to open its properties; then go to 'data' and select the 'density' variable)
7. make sure 'resample outline' and 'resample lines only' are selected and then run so only your outline will be resampled.
8. drag and drop the resampled outline as the new outline in your first mesh generator (where you created the bigger mesh with). Deselect 'resample outline' and run again. The mesh that is now created should give you a satisfying result.
I would recommend playing with this to create first some small meshes, because for large meshes it can take quite some time.
I hope you can get some nice results with this
