Non-local

*Non-local, elset = <set name, local-len = <local length>, statev = <local length> [, time] [, frequency =<>]
<list of total time at which a non-local smoothing is performed, separated by comma>

With this keyword state variables are smoothed spatially. The keyword is defined within a Step environment. The user has to make the following definitions:

  • elset

    The element set for which the smoothing is performed.

  • local-len

    The local-length for which the smoothing is performed. The smoothing accounts for points with an approximate maximum distance of two-times the local-length to the smoothed point.

  • statev

    The number of state variable which is smoothed. For the hypoplastic model, for instance, statev=1 would smooth the void ratio.

The following optional statements can be made:

  • time

    The total time at which the smoothing is performed. The time has to be given in the subsequent line with multiple values separated by comma.

  • frequency

    The frequency in terms of increments at which a smoothing is performed. No subsequent line exists.

Either time or frequency has to be defined.
