An automatic differentiation (AD) technique and implementation processes multi-physics solver code entirely on graphics processing units (GPUs) to automatically differentiate one or more outputs of the code with respect to one or more inputs. The technique provides a “factory” framework that ingests arbitrarily complex solver code to produce a version of the code that is automatically differentiated (AD code) and mapped to the GPUs. The technique provides a derivative of the solver code output with respect to the inputs that enables analysis of the output of the computed solver code with initially provided inputs coherent with sensitivity analysis of that output as the inputs are changed. The adjoint information derived from solver code execution (AD code) computed by the AD technique may also be used to estimate one or more estimates of the numerical error in a solution to the physical simulation.
