Import data from Femap Neutral files.
f=readneu
f=readneu(filename,datasets,'silent')
f=readneu('neutral_file.neu',[403 404])
f=readneu('silent')
f=readneu('noprogbar')
READNEU reads datasets from Femap Neutral (.neu) files.
FILENAME is an optional input string containing the filename to read. If not supplied, you will be prompted for the filename with a graphical dialog.
DATASETS is an optional numeric vector containing the dataset numbers to import. If the dataset number is negative, READNEU will read datasets except for that one. For example, if DATASETS is -404, READNEU will read all datasets except for dataset 404.
Passing in the string 'silent' suppresses output to the screen during processing.
Passing in the string 'noprogbar' suppresses the progress bar during processing.
The following datasets are supported:
| Dataset Number | Description | Notes |
|
403 |
Node | |
| 404 | Element | See below for a detailed list of supported element types. Note that properties from dataset 402 will be imported and applied to the element output if it exists. |
|
405 |
Coordinate system | |
| 408 | Groups | |
| 2208 | Groups | Femap 2022.2+ |
F is a cell array containing the outputs. FEM entities will be returned as an imat_fem, and group entities will be returned as an imat_group. If nothing was read, DATA will be -1.
READNEU does not support all element types. The following table lists the element types not currently supported.
