READ_VEL read a FEM output file of .vel filetype. |
|---|
| 12 |
READ_VEL is part of a suite of OPNML I/O functions |
|---|
| 13 |
to read specific filetypes pertaining to FEM model |
|---|
| 14 |
input and output. These functions allow the user to |
|---|
| 15 |
get these data files into MATLAB without copying the |
|---|
| 16 |
files and removing the header info by hand. |
|---|
| 17 |
|
|---|
| 18 |
READ_VEL reads the FEM filetype .vel, as detailed in |
|---|
| 19 |
"Data File Standards for the Gulf of Maine Project" |
|---|
| 20 |
from the Numerical Methods Laboratory at Dartmouth |
|---|
| 21 |
College. (This document is located in the OPNML |
|---|
| 22 |
notebook under External Documents.) There are eight |
|---|
| 23 |
columns, the first of which is the node number. The |
|---|
| 24 |
remaining columns are floating point. |
|---|
| 25 |
|
|---|
| 26 |
Input : If fname is omitted, READ_VEL enables a file browser |
|---|
| 27 |
with which the user can specify the .vel file. |
|---|
| 28 |
|
|---|
| 29 |
Otherwise, fname is the name of the .vel file, relative |
|---|
| 30 |
or absolute (fullpath), including the suffix '.vel'. |
|---|
| 31 |
This input is a string so it must be enclosed in single |
|---|
| 32 |
quotes. The header lines are discarded. |
|---|
| 33 |
|
|---|
| 34 |
Output : The data part is returned in the variable data. |
|---|
| 35 |
There are eight columns, the first of which is the node |
|---|
| 36 |
number. The remaining columns are floating point. |
|---|
| 37 |
The number of vertical nodes is returned in nnv, and |
|---|
| 38 |
the frequency is returned in freq. |
|---|
| 39 |
|
|---|
| 40 |
Call READ_VEL as: |
|---|
| 41 |
>> [data,nnv,freq]=read_vel(fname); |
|---|
| 42 |
|
|---|
| 43 |
If READ_VEL cannot locate the file, it exits, returning |
|---|
| 44 |
a -1 instead of the data matrix. |
|---|
| 45 |
|
|---|
| 46 |
NOTES : The .vel filetype contains 3-D data; i.e., complex-valued |
|---|
| 47 |
velocity data at each vertical node per horizontal node. |
|---|
| 48 |
The .vel file has phase in radians while the related .<A HREF = "../4.IO_Functions/v3c.html">v3c</A> |
|---|
| 49 |
format has phase in degrees. |
|---|
| 50 |
|
|---|
| 51 |
Call as: [data,nnv,freq,gridname]=read_vel(fname); |
|---|
