[ANN] LowLevelFEM.jl v1.14.2 – Contact mechanics directly from weak forms

Contact mechanics — almost exactly as written on paper! LowLevelFEM.jl now supports 2D and 3D contact mechanics using penalty and Lagrange-multiplier formulations. The framework also provides the building blocks for frictional contact, allowing more advanced contact laws to be implemented directly at notebook level. The idea is simple: write the weak form, assemble the operator, solve the problem. For penalty contact, the contact stiffness is K_c = \int_{\Gamma_c} G^T c_n G\,d\Gamma And in...
