2D stiffness matrix calculation is ported to FemApp solver. Based on a simple tria mesh, displacement and reaction force results are coherent with the ones from Nastran 🥳 Next step is to combine this with the tria mesher in Unity 🤔

I've made some visual additions to 2D tria mesher, like coloring of element numbering, wire-frame mesh display, identification of edge nodes 🧐 It's getting prettier ^^

I implemented calculations of 2D stiffness matrix for any given triangle and deformed shape under any loading on Excel. 🎉 Next step is to port this to C# and apply it to tria mesh to build global matrices and deformations. 🤔🤨

2D tria mesher of my new engineering app which is under development, now has capability to smooth the mesh. 😎 Here is a video that shows the resulting mesh topologies in Unity. 👀 🥳
