MONSUM

Bulk Data Entry Defines a new monitor result that is the weighted sum of existing monitor results.

The existing monitor points do not need to be of the same type but must be of a similar type. The results are printed to the .monpnt file.

Definitions

Field Contents SI Unit Example
NAME Character string identifying the monitor point.

No default (Character, a maximum of 8 characters)
LABEL A character string that identifies and labels the monitor point.

Default = blank (Character, a maximum of 56 characters, fields 3 through 9)
NEWAXIS The component axis of the newly created monitor point into which the summed quantity is scored.

(Integer > 0, up to six unique digits (0 < digit ≤ 6) may be placed in the field with no embedded blanks)
MTYPEij Monitor type to be merged.

No default (AMONPNT1, AMONDSP1, SMONPNT1, SMONDSP1)
NAMEij Name of the monitored quantity that is to be merged.
AXESIJ Component axis to be summed.

(Integer > 0, up to six unique digits (0 < digit ≤ 6) may be placed in the field with no embedded blanks)
COEFij Coefficient to be applied to the component(s) called out on AXESij field.

Default = 1.0 (Integer > 0)

Comments

  1. The MONSUM entry is supported for linear static analysis only.
  2. You can use MONSUM to update an existing monitor result by setting all the NAMEij terms equal to NAME. In this case, the alternate format is available, and the NEWAXISj component is a scalar multiple of the original component: MONSUMj = MRj COEFj
  3. When the NAME differs from the NAMEij values, it must be unique for all monitor quantities. The result of the MONSUM entry is to create new monitor points that are equal to:
    MONSU M j  =  ∑ i n COE F ij M R ij MathType@MTEF@5@5@+= feaahGart1ev3aaatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbuLwBLn hiov2DGi1BTfMBaeXatLxBI9gBaebbnrfifHhDYfgasaacH8srps0l bbf9q8WrFfeuY=Hhbbf9v8qqaqFr0xc9pk0xbba9q8WqFfea0=yr0R Yxir=Jbba9q8aq0=yq=He9q8qqQ8frFve9Fve9Ff0dmeWabaqaciGa caGaaeqabaqaaeaadaaakeaacaWGnbGaam4taiaad6eacaWGtbGaam yvaiaad2eadaWgaaWcbaGaamOAaaqabaGccaaMc8Uaeyypa0JaaGPa VpaaqahabaGaam4qaiaad+eacaWGfbGaamOramaaBaaaleaacaWGPb GaamOAaaqabaGccaWGnbGaamOuamaaBaaaleaacaWGPbGaamOAaaqa baaabaGaamyAaaqaaiaad6gaa0GaeyyeIuoaaaa@490A@
  4. The merged monitor points must be of a similar type. "Similar" types are defined as:
    • Force and moment summation monitor points: AMONPNT1, SMONPNT1, and MONPNT3.
    • Average displacement monitor points: AMONDSP1 and SMONDSP1.
  5. For MONPNT1s and MONDSP1s, the MTYPij can be aerodynamic or structural. MTYPij = AMxxx1 designates aerodynamic, while SMxxx1 designates a structural monitor point.
  6. If multiple components are to be summed, the NEWAXISj field must be the union of subsequent AXESij fields. If the subsequent AXESij field is blank, the components are determined from NEWAXISj.
  7. If the NEWAXISj field indicates a single output, the AXESij fields must reference a single input, but it can be any value from 1 to 6.
  8. The same component cannot be referenced multiple times on the NEWAXISj field for a single MONSUM entry.
  9. If multiple types are specified on a MONSUM entry, the resulting entry is of a type that appears on the MONSUM with the following order of precedence: SMONPNT1, SMONDSP1, MONPNT3, AMONPNT1, AMONDSP1. For example, an AMONPNT1 and a MONPNT3 appearing on the same entry will result in a MONPNT3 regardless of which appears first.
  10. If all the MTYPij values are of the same type, the alternate format provides a simplified interface.
  11. MONPNT3s with one, two, or three excluded items (for example, XFLAG = SMA) cannot be referenced on a MONSUM entry.
