A method of constructing parameterized nonintrusive reduced‐order models (NIROMs) is given. The approach relies on a geometrical interpretation of NIROM, requires only a single layer of interpolation to be applied for both system state and parametric dependence of the model and is applicable to systems characterized by any number of parameters spanning arbitrary orders of magnitude. The method is applied to three representative test problems and evaluated in terms of accuracy and speed, showing good performance.

一种有效且鲁棒的参数化非侵入式降阶建模方法

给出了构造参数化非侵入式降阶模型（NIROM）的方法。该方法依赖于NIROM的几何解释，仅需对系统状态和模型的参数依赖性都应用单层插值，并且适用于以任意数量的参数跨越任意数量级为特征的系统。该方法应用于三个代表性的测试问题，并在准确性和速度方面进行了评估，显示出良好的性能。
