**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
