forward problem Electronics and Electrical Engineering
The problem of obtaining predictions of the output of some physical process by supplying a model of this process with appropriate input parameters. This is usually straightforward because the models are designed to predict outputs based on inputs. See alsoinverse problem.
Geology and Earth Sciences
The problem of calculating what should be observed for a particular model, e.g. calculating the gravity anomaly that would be observed for a given model of a salt dome. Compareinverse problem.
