We implement a self-consistent Hartree full-band envelope-function method in kdotpy. Our method maintains numerical stability where standard theories fail. We demonstrate quantitative accuracy by matching experiments on HgTe quantum wells, providing an essential tool for investigating narrow-, broken-, and inverted-gap systems.
