Improvement & Corrections ✓ Mixable-Density Topology Optimization • Thermal-load in Static Analysis is supported in 23r1. The handling is fully consistent between Level-set, Mixable-Simp, Shape opt. and Topography. • Correction in the computation of the derivative for static criteria in the presence of acceleration. • Three advanced parameters are available : "initial volume fraction", "penalty factor" and "hyperbolic projection" ✓ Level-set Topology Optimization • Many improvements have been introduced leading to a faster machinery. The computation per iteration is more than 2x faster. ✓ Multi Optim Type Strategy • A special tuning has been introduced to handle the mix of optimization methods. This new tuning is automatically activated for this context • It can also be used for single optim method. It will affect the behavior of Level-Set and Shape Optimization. • The strategy is more agressive and leads to better and faster results, but possibly less smooth. Thermal load with Mix-Simp Multi Optim Strategy = off nb iterations: 61 final compliance: 0.340J Multi Optim Strategy = ON nb iterations: 36 final compliance: 0.338j
