Profile consistency (or profile resilience) is the observation that profiles (of temperature, density, and pressure) often tend to adopt roughly the same shape (in tokamaks), regardless of the applied heating and fueling profiles. | Profile consistency (or profile resilience) is the observation that profiles (of temperature, density, and pressure) often tend to adopt roughly the same shape (in [[Tokamak|tokamaks]]), regardless of the applied heating and fueling profiles. | ||
