Table 6-64: Valid Modal Properties for the POD Reduction.
Property	Value	Default	Description
analysistype	frequency \| transient	transient	Solve for frequency response or transient response.
clist	String array		Provide values for constants as input parameters using a string array; for the corresponding constant names, use cname. See The clist and cname Properties.
cname	String array		Provide names of constants as input parameters using a string array; for the corresponding constant values, use clist. See The clist and cname Properties.
constrmodes	array of integers		The constraint modes to use, if constrmodeselection is set to manual.
constrmodeselection	all \| manual	all	The constraint modes to use.
constrsol	solution object or none		The solution to use for the constraint modes.
control	String	user	Name of the controlling study step or user if the feature is controlled manually.
groupmethod	one \| individual \| manual	one	Variable grouping method for training solution: one group, one group per variable, or manual.
keeplog	on \| off	off	Keep warnings in stored log.
linearity	false \| linper	false	Use linear linearity or a linear perturbation when analysistype has been set to frequency.
