1. A method for modeling dynamic systems, said method comprising: constructing an input parameter space for a model of a geological system with a computer system, said input parameter space including more than three dimensions, and said model associated with response data, wherein the input parameter space comprises a plurality of input parameters that each has a range of values and said response data is generated from the model and one or more of the plurality of input parameters; representing said input parameter space visually, with said computer system, with fewer dimensions than a number of dimensions of said input parameter space by using a subset of said response data; conditioning said input parameter space to reduce a size of said input parameter space by using at least said subset of said response data and measured data associated with said geological system, said conditioning comprising: defining a constraint associated with said response data; creating one or more regions around said response data that satisfies said constraint; displaying said one or more regions in said visual representation of said input parameter space; and narrowing one or more ranges of said plurality of input parameters based on the one or more regions; and updating said representation of said input parameter space to visually represent said reduction of said input parameter space.
