FEM.edu-v1.0.30-3.20.25

New with this Release

• Triangle, Triangle6 available for linear and finite deformation analyses.
• Quad, Quad9 available for linear and finite deformation analyses.
• Sparse solver for nonlinear analyses providing speed-up and allows for much larger problems than previous versions.
• Beam-solid coupling.
• 2d false color plots for all 2d elements.
• Geometry-based detection of nodes and faces for easy generation of fixities and surface loads.
