subsets of the model. You can then process these smaller files on your local machine. For example, if
your large model is an assembly, you can create individual results files for each part.

You can also use this capability to create a subset of results for efficient postprocessing. For example,
you could take the results file from a large model that had all results written, and create a smaller results
file containing only stresses on the exterior surface. This smaller file would load and plot quickly, while
not losing any of the detailed data written to the full results file.

When you use this feature, the subset geometry is also written to the results file so that you do not
need the database file (no SET required). However, you must not resume any database when postpro-
cessing one of these results files, and your original results file must have the geometry written to it (i.e.,
do not issue /CONFIG,NORSTGM,1).

To use the results file splitting feature:
Command(s):RSPLIT
GUI: Main Menu> General Postproc>
You can use this feature in conjunction with INRES to limit the amount of data written to the results
files.

A brief example of how you might use this feature is shown below:

/POST1

FILE,jobname,rst! Import *.rst file

ESEL,all

INRES,nsol,strs! Write out only nodal solution and stresses

RSPLIT,ext,esel,myexterior! Write the results for the exterior of the whole model to a file

! named myexterior.rst

FINISH

/EXIT

/POST1

FILE,myexterior

PLNS,s,eqv! Postprocess the myexterior.rst file as usual

PLNS,u,sum

FINISH

7.3.7. Magnetics Command Macros

The following magnetic command macros are also available for calculating and plotting results from a
magnetic analysis:

• CURR2D (Main Menu> General Postproc> Elec&Mag Calc> Element Based> Current) calculates
  current flow in a 2-D conductor.


• EMAGERR (Main Menu> General Postproc> Elec&Mag Calc > Element Based> Err or Eval) calculates
  the relative error in an electrostatic or electromagnetic field analysis.


• EMF (Main Menu> General Postproc> Elec&Mag Calc> Path Based> EMF) calculates the electro-
  motive force (emf ) or voltage drop along a predefined path.


• EMFT (Main Menu> General Postproc> Elec&Mag Calc> Path Based> EMF) summarizes electro-
  magnetic forces and torques on a selected set of nodes.


• FLUXV (Main Menu> General Postproc> Elec&Mag Calc> Path Based> Path Flux) calculates the
  flux passing through a closed contour.


• FMAGBC (Main Menu> Preprocessor> Loads> Define Loads> Apply> Electric> Flag> Comp.
  Force) applies force boundary conditions to an element component.
