**process norm

Description

The norm post processor is used to norm a tensor or scalar variable. It returns a variable of the same type (tensor or scalar) with name constructed by pre-fixing the original variable name(s) with an N.

Syntax

**process norm \(~\,\) *var name [ *type tensor | scalar ]

The user must give a material coefficient sigma_u. The coefficient can be constant or depend on other parameters.

Example

% this will provide 4 components :
% Nsig11, Nsig22, Nsig33 and Nsig12
**process norm
  *var sig

% the following syntax must be used in the material file:
**process norm
  sigma_u  170.
