Number of Viscoelastic Modes#

Number of viscoelastic modes = <integer>

Description / Usage#

This card is required only if you are performing a viscoelastic simulation and have included stress equations in the equation section and chosen a viscoelastic constitutive equation in the material file. The integer value denotes how many viscoelastic tensor stress equations are to be used. The number of modes can vary from a minimum of 1 to a maximum of 8. The input parameter is defined as

The number of viscoelastic modes, which must be greater than zero, but less than nine.

Examples#

The following is a sample card, indicating that a calculation with two viscoelastic stress modes is being undertaken:

Number of viscoelastic modes = 2
