* exgfrm - ex_get_coordinate_frames: read coordinate frames
|
|
*
|
|
* author - Sandia National Laboratories
|
|
* Garth Reese - created this function. Nov 2002
|
|
*
|
|
* environment - UNIX
|
|
*
|
|
* entry conditions -
|
|
* input parameters:
|
|
* int exoid exodus file id
|
|
*
|
|
* NOTE:
|
|
* cf_ids, pt_coordinates and tags may all be NULL, otherwise, they
|
|
* must have sufficient memory to store the output data. Two calls
|
|
* to this routine are anticipated (one to get nframes, the second
|
|
* to fill the data. i.e.
|
|
* ex_get_coordinate_frames(exoid,&nframes,0,0,0);
|
|
* ... allocate memory ...
|
|
* ex_get_coordinate_frames(exoid,&nframe,id,coords,tags);
|
|
*
|
|
*
|
|
* output conditions -
|
|
* int* nframes number of coordinate frames in model
|
|
* const int* cf_ids coordinate ids
|
|
* dimension int[nframes]
|
|
* const void* pt_coordinates pointer to coordinates. 9 values per
|
|
* coordinate frame
|
|
* dimension float[9*nframes]
|
|
* const char* tags character tag for each frame.
|
|
* 'r' - rectangular
|
|
* 'c' - cylindrical
|
|
* 's' - spherical
|
|
* dimension char[nframes]
|
|
*
|
|
* returns -
|
|
* EX_NOERR for no error
|
|
* EX_FATAL for fatal errors
