Parameters

Name: Type: System String
The name of an existing material property.

ModalRatio: Type: System Double
The modal damping ratio.

ViscousMassCoeff: Type: System Double
The mass coefficient for viscous proportional damping.

ViscousStiffCoeff: Type: System Double
The stiffness coefficient for viscous proportional damping.

HystereticMassCoeff: Type: System Double
The mass coefficient for hysteretic proportional damping.

HystereticStiffCoeff: Type: System Double
The stiffness coefficient for hysteretic proportional damping.

Temp (Optional): Type: System Double
The temperature at which the specified data applies. The temperature must have been previously defined for the material.
This item applies only if the specified material has properties that are temperature dependent. That is, it applies only if properties are specified for the material at more than one temperature.

Return Value

Returns zero if the data is successfully assigned; otherwise it returns a nonzero value.
