# Re-mesh at each frequency.
In a parametric sweep, one or more user defined [[variables]] are varied at the same time over their specified ranges. This creates a parametric space with the total number of samples equal to the product of the number of samples for each variable. The user defined [[variables]] are defined using [[EM.Cube]]'s '''[[Variables]] Dialog'''. For a description of [[EM.Cube]] [[variables]], please refer to the "Parametric Modeling, Sweep & [[Optimization]]" section of [[EM.Cube]] Manual or see the "Parametric Sweep" sections of the FDTD or [[Planar Module]] manuals.
