Z88Tina is a real Finite-Elements program for finite elements analysis (FEA) featuring not only Beams and Trusses in space and plane but also full-featured continuum FEA elements like Plane Stress elements, Axisymmetric elements and Reissner-Mindlin Plate elements with an isoparametric quadratic Serendipity approach with 6 nodes each.
Z88Tina is a very, very small cousin of our full-featured freeware FEA program Z88Aurora (www.z88.de) and is derived from the open source FEA program Z88V14OS.
Z88Tina can operate in two modes: either with interactive input of the structure or by loading a structure composed on a PC. It includes a very comprehensive online help via Internet with several examples, additional examples on Z88Tina's home page (www.z88tina.de) with a pdf manual. It features a Cholesky solver well suited for small to medium sized equation systems and quite nice OpenGL graphics for investigating the results.
