`**process node_extrapolation`#

Description#

This post-computation extrapolates integration point data to either the nodes ( format), or to the element nodes ().

**process node_extrapolation \(~\,\) *list_var name1 … nameN [ *output_var o-name1 … o-nameN ] [ *ctele | *ctnod ]

*list_var name1, … , nameN: are the scalar variable names to treat. The input data is read in the results files problem.integ. The calculated results are stored in the file problem.ctnodp.
*output_var o-name1 … o-nameN: These output variables are named gpname1, … gpnameN, or o-name1 … o-nameN if they were specified.
*ctele: The output extrapolated results will be stored at each node within every element.
*ctnod (By default): The output extrapolated results will be stored in nodes (averaged).
