Keyword type: step
This procedure is used to perform a static analysis for materials with viscous behavior. The syntax is identical to the *STATIC syntax. Notice that the default way of applying loads in a *VISCO step is step loading, i.e. the loading is fully applied at the start of the step. This is different from a *STATIC step, in which the loading is ramped. Using a *VISCO step only makes sense if at least one materials exhibits viscous behavior.
