P: normalA defect affecting operation with a low possibility of significantly affects.T: defectAn anomaly, which is anything that deviates from expectations.
When using automatic_scaling or "manual" scaling of variables, the adjoint system doesn't scale properly. While the gradients for the optimization will point in the correct direction they can become scaled such that gradient tolerances become useless.
Steps to Reproduce
Turn on automatic scaling and observe convergence criteria.
Impact
This can make the working with coupled physics hard when scaling is especially useful.
