i1: i*4: Material ID of quiet or powder elements
This option allows for use of a material ID to define the material properties of quiet or powder elements. When used, quiet elements are assigned this material ID initially. After the elements are switched to active, the element material ID is switched to that of the solid material. When *DDMM is used, no scaling of properties is used for quiet elements (Values defined by *DDM1 are ignored).
Currently implemented for thermal analysis only.
