== An Overview of HDMR Method ==
[[Image:Variable30.png|thumb|400px|Choosing HDMR sweep as the simulation mode in the Simulation Run dialog.]]
In the HDMR method, you run successive evaluations of a given function of one or more [[variables]] for a number of [[variables]] samples. Then you create an optimal monomial surface representation of the computed data as a function of those [[variables]]. The resulting simplified function is characterized by a finite number of monomial coefficients. Therefore, its computation is more faster and computationally efficient than the original functions.
==Defining HDMR Variables ==

To define the HDMR [[variables]], follow the procedure below:
* Open the '''Run Dialog''' of most of [[EM.Cube]]'s computational modules and select the '''HDMR''' option from the '''Simulation Mode''' dropdown list.
