Create mesh from intersecting closed curves

Grasshopper
1

Hello everyone,

new to the forum and Rhino/Grasshopper. I am trying to build a meshed geometry for a plane strain FE model and to generate an Abaqus Input file for it. I built and blended all the different curves I needed in order to create a section of the structure I want to analyse. I have been unable to create a surface enclosed in the intersecting curves and to mesh it. I tried to use Boundary surfaces, receiving warnings and a surface which encloses only part of the geometry.

Thank you for the kind help.

Please bring your example down to a smaller version. Not using plugins, so we can see what it is about.

Hi.
I simplified the geometry. I want to obtain a surface in the closed area highlighted in blue. The more the geometry becomes complex, although planar, the more the surface creation is far from the desired result.
