MESHF
Bulk Data Entry Defines options for user-defined input of frequency ranges used to define bands in adaptive meshing for acoustic Adaptive Perfectly Matched Layer (APML) analysis.

Example
As shown in the example below, FVAL and FRNG do
not need to be defined in any particular order. Five frequency bands are defined in
this example: [10.0,10.0], [20.0,40.0], [41.0,41.0], [50.0,50.0], [51.0,80.0]

|---|---|---|---|---|---|---|---|---|---|
| MESHF | 7 | FVAL | 10.0 | FRNG | 20.0 | 40.0 | |||
| FVAL | 41.0 | FVAL | 50.0 | ||||||
| FRNG | 51.0 | 80.0 |
Definitions
| Field | Contents | SI Unit Example |
|---|---|---|
| MFID | Mesh frequency identification number. This can be referenced
on the MFID field of PACPML Bulk Data. No default (Integer > 0) |
|
| FVAL | Flag indicating that a single frequency value (F) is to follow. | |
| F | Single frequency value to be a part of the frequency bands.
No default (Real) |
|
| FRNG | Flag indicating that two frequency values (F1, F2) are to follow. | |
| F1, F2 | Two frequency values identifying a frequency range that
defines a frequency band. No default (Real) |
Comments
- Any number of FVALs and FRNGs can be defined on this entry.
