numexp#
- Mapdl.numexp(num='', begrng='', endrng='', elcalc='', **kwargs)#
Specifies solutions to be expanded from mode-superposition analyses or
APDL Command: NUMEXP substructure analyses.
- Parameters:
- num
The number of solutions to expand. This value is required.
- Num
Number of solutions to expand.
- ALL
Expand all substeps between
BEGRNG
andENDRNG
(provided that ENDRNG > 0). IfBEGRNG
andENDRNG
have no specified values, this option expands all substeps of all load steps.
- begrng, endrng
Beginning and ending time (or frequency) range for expanded solutions. The default is 0 for both values.
- elcalc
The element-calculation key:
- YES
Calculate element results, nodal loads, and reaction loads. This value is the default.
- NO
Do not calculate these items.
Notes
Specifies a range of solutions to be expanded from analyses that use mode-superposition methods (
ANTYPE,HARMIC
orTRANS
) or substructuring (ANTYPE,SUBSTR
).For ANTYPE,TRANS, NUM, evenly spaced solutions are expanded between time BEGRNG and time
ENDRNG
.For ANTYPE,HARMIC, NUM, evenly spaced solutions are expanded between frequency BEGRNG and frequency
ENDRNG
.The first expansion in all cases is done at the first point beyond BEGRNG (that is, at
BEGRNG + (ENDRNG - BEGRNG) / NUM
)).The resulting results file will maintain the same load step, substep, and time (or frequency) values as the use pass.
For a single expansion of a solution, or for multiple expansions when the solutions are not evenly spaced (such as in a mode-superposition harmonic analysis with the cluster option), ANSYS, Inc. recommends issuing one or more
EXPSOL
commands.The NUMEXP command is invalid in these cases:
In a substructing analysis (
ANTYPE,SUBST
) when a factorized matrix file (the.LN22
file generated by the sparse solver) does not exist, causing ANSYS to employ the full-resolve method.If the full-resolve option is selected using the
SEOPT
command.In both situations, use the
EXPSOL
command to perform a single expansion for each solution desired.This command is also valid in PREP7.
