Are you suffering from slow animations with large FEM results?
Do you need to navigate into huge FEM DoE where full result would be TB of data?
💡 Rather than storing full results and animating the usual skin mesh, SDTools is finding many industrial reasons to store reduced models, perform restitution on the fly and animate cuts (slices)
💿 These reasons are illustrated on a full brake FEM from HitachiAstemo with 1.8 million DOF
🍃 Lighter animations
👉 836 nodes rather than 607 000 nodes using cuts + to feature preserving mesh coarsening
🔎 View internal motion / hide less surfaces
👉 The piston and pins are only visible with the cuts
💾 Limit memory usage and file sizes
👉 Interactive viewing of large data sets: use generalized DOF (1 GB = 400 000 complex shapes on 168 generalized DOF, but <40 on all 1.8 million DOF)
👉 Restitution on the fly (simulations MATLAB, SimuLink) or expand test results (testlab, Polytec, SDT, HybridTwin) takes micro-seconds since display mesh is small
👉Animation file: reduced DOF superelement allowing restitution of any shape on the reduced mesh (3.4 MB in comparison with initial FEM superelement with restitution on full mesh 2.3 GB)
⚙️ This strategy integrates fluently in your processes
👉 FEM software neutral format, imported from NASTRAN, Ansys, Abaqus, … superelements in any form (free-modes with residual vectors, Craig-Bampton, …) or generated with SDT
👉 Share your animation without giving your model. As a supplier you may want to preserve your intellectual property: mesh slicing and coarsening hides much detail
