"Assembly" of elements of different dimensionalities (1-D, 2-D)

Click For Summary
SUMMARY

The discussion focuses on the assembly of 1D and 2D elements in computational modeling, highlighting the differences in degrees of freedom at nodes. The assembly procedure for mixed-dimensional meshes requires a nuanced understanding of algebraic topology, geometry, and graph theory. Participants emphasize the importance of specificity in queries to facilitate effective assistance. The conversation underscores the complexities involved in integrating different dimensional elements within a single framework.

I am currently working on a problem which involves both 1D and 2D elements. I know that these elements have different degrees of freedom at a node and, therefore, the procedure of assembly of elements will different from a purely 1D or a purely 2D mesh. I don't know the rest of the details. Any help will be greatly appreciated.

I sounds like you're touching upon the idea of a simplex and/or polytope from the subjects of algebraic topology, geometry, and graph theory. But your query is quite vague. Could you ask a more specific question or give some context?
