NUMEXP, NUM, BEGRNG, ENDRNG, Elcalc
Specifies solutions to be expanded from reduced analyses.
MP ME ST PR PRN <> <> <> <> <> <> PP <>
The number of solutions to expand. This value is required.
Num | — | Number of solutions to expand. |
ALL | — | Expand all substeps between BEGRNG and ENDRNG (provided that ENDRNG > 0). If BEGRNG and ENDRNG have no specified values, this option expands all substeps of all load steps. |
Beginning and ending time (or frequency) range for expanded solutions. The default is 0 for both values.
The element-calculation key:
YES | — | Calculate element results, nodal loads, and reaction loads. This value is the default. |
NO | — | Do not calculate these items. |
Issuing this command with no arguments is invalid. You must specify the number of solutions, or all solutions, to expand (NUM). The default value for both the beginning (BEGRNG) and ending (ENDRNG) time or frequency is 0. The default behavior of the command is to calculate element results, nodal loads, and reaction loads (Elcalc = YES).
Specifies a range of solutions to be expanded from analyses that use reduced or mode superposition methods (ANTYPE,HARMIC, TRANS, or 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)).
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 recommends issuing one or more EXPSOL commands.
The NUMEXP command is invalid in these cases:
In a substructing analysis (ANTYPE,SUBST) when a triangularized matrix file (the .TRI file generated by the frontal solver or 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.
