Commercial structural optimization is decades old, and the solvers behind it earned their reputations. The experience around those solvers is another matter. Setup is still card-based and takes years to master. Licensing is hard to predict without a spreadsheet. The preprocessor, solver, and postprocessor come from different eras and were never designed together. Meanwhile the vendors keep consolidating into larger enterprise suites, where a structural optimizer becomes one line item among hundreds.
We think the numerics deserve a better vehicle. PGD is independent, and optimization is our whole product: a modern solver, analytic sensitivities, a scriptable workflow that treats your model as code, and software that runs wherever your data is allowed to live.
