Explore the saved OOFEM steel-joint solution, its changing stress field, and the moment required to rotate the loaded control node.
What is modelled
The supplied input uses a steel J2 plasticity material with elastic modulus 210,000, Poisson’s ratio 0.3, and yield stress 275 in its N–mm unit convention. It also defines an interface damage material. The viewer displays the exported tetrahedral region; other input elements not included in the VTU are not reconstructed.
Although the files are stored under CalculiX, the input and solver log identify this run as OOFEM. Von Mises stress is calculated from the exported nodal stress tensor.
Deformed shape and playback
The deformed_x2 files already contain coordinates amplified by two. This viewer recovers the original geometry from the matching unwarped export, then applies the scale exactly once. The default ×2 matches your files; choose True scale ×1 for the physical displacement or ×0 for the reference mesh.
Playback interpolates all 58 saved states. Only exterior faces and their nodes are transferred to the browser, with shared topology and compressed frame data. No symmetry copies are introduced. Stress colours rescale at each frame; consult the numerical legend.
Moment–rotation and run limits
The synchronized curve uses the saved moment_rotation.csv: the magnitude of node 50004 rotation in milliradians, and moment magnitude in kN·m. The supplied plotting script converts the reached load factor using a reference moment of 1e6 N·mm. The export index starts at zero, corresponding to solution step 1.
The input requests 80 steps, but only 58 result states are available. The solver log ends with an error and iterative-solver warnings. The displayed curve is therefore a partial saved response, not evidence of successful completion or ultimate joint capacity. No later states or zero-load point have been added.
