EnSight User Defined Reader Capability
|
|
|
|
|
--------------------------------------
|
|
|
|
|
|
|
|
|
|
A user defined reader capability is included in EnSight which allows otherwise
|
|
|
|
|
unsupported structured or unstructured data to be read. The user defined
|
|
|
|
|
reader utilizes a dynamic shared library composed of routines defined in this
|
|
|
|
|
document, but produced by the user (or some third party). This capability is
|
|
|
|
|
currently available for dec, ibm, hp, sgi, and sun servers.
|
|
|
|
|
|
|
|
|
|
****************************************************************************
|
|
|
|
|
Note: Several user defined readers have been included with your EnSight
|
|
|
|
|
release and can be accessed by changing the ENSIGHT6_READER
|
|
|
|
|
environment variable as outlined in step 3. below. Please be aware
|
|
|
|
|
that these are "unsupported" readers, but many of them are being used
|
|
|
|
|
successfully.
|
|
|
|
|
****************************************************************************
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
The process for producing a user defined reader is:
|
|
|
|
|
--------------------------------------------------
|
|
|
|
|
1. Write code for all pertinent routines in the library (Unless someone else
|
|
|
|
|
has done this for you).
|
|
|
|
|
|
|
|
|
|
This is of course where the work is done by the user. The word
|
|
|
|
|
"pertinent" is used because depending on the nature of the data, some
|
|
|
|
|
of the routines in the library may be dummy routines.
|
|
|
|
|
|
|
|
|
|
The source code for a dummy library and for various other working or
|
|
|
|
|
sample libraries is copied from the installation CD during
|
|
|
|
|
installation. These will be located in directories under:
|
|
|
|
|
|
|
|
|
|
$ENSIGHT6_HOME/ensight62/user_defined_src/readers

You may find it useful to place your library source in this area as
|
|
|
|
|
well, but are not limited to this location.
|
|
|
|
|
|
|
|
|
|
* ===> The descriptions of each library routine and the order that the
|
|
|
|
|
routines are called, which is provided in this file, along with
|
|
|
|
|
the example libraries, should make it possible for you to produce
|
2013-07-18 01:02:34 +00:00
|
|
|
code for your own data reader.
|
2010-05-12 13:27:55 +00:00
|
|
|
|
|
|
|
|
|
|
|
|
|
2. Produce the dynamic shared library.
|
|
|
|
|
|
|
|
|
|
This is a compiling and loading process which varies according to
|
|
|
|
|
the type of machine you are on. Thus, a separate makefile is provided
|
|
|
|
|
for each machine type. Operating system level differences could cause
|
|
|
|
|
you to have to modify these makefiles slightly, but the general
|
|
|
|
|
process is very straightforward. Note that for the SGI environment you
|
|
|
|
|
must compile with the following flags to ensure compatability with
|
|
|
|
|
the EnSight server: Irix_5.3 -mips1
|
|
|
|
|
Irix_6.2 -mips2
|
|
|
|
|
Irix_6.5_n32 -mips3
|
|
|
|
|
Irix_6.5_n64 -mips4 -64

Once you have created your library, you should place it in a directory
|
|
|
|
|
of your choice under:
|
|
|
|
|
|
|
|
|
|
$ENSIGHT6_HOME/machines/$ENSIGHT6_ARCH/lib_readers
|
|
|
|
|
|
|
|
|
|
Thus, if you created a reader for "mydata", you should create the
|
|
|
|
|
following directory, and place your libuserd.so into it:
|
|
|
|
|
|
|
|
|
|
$ENSIGHT6_HOME/machines/$ENSIGHT6_ARCH/lib_readers/mydata
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
3. Set up the ENSIGHT6_READER environment variable so EnSight will know
|
|
|
|
|
which reader directory to use at runtime.
|
|
|
|
|
|
|
|
|
|
Ensight will look for the library under:
|
|
|
|
|
|
|
|
|
|
$ENSIGHT6_HOME/machines/$ENSIGHT6_ARCH/lib_readers/$ENSIGHT6_READER
|
|
|
|
|
|
|
|
|
|
When EnSight was installed, you set this variable to "dummy", with:
|
|
|
|
|
|
|
|
|
|
setenv ENSIGHT6_READER dummy
|
|
|
|
|
|
|
|
|
|
You can use any of the other provided readers by changing this variable.
|
|
|
|
|
For example, to use the dytran reader:
|
|
|
|
|
|
2013-07-18 01:02:34 +00:00
|
|
|
setenv ENSIGHT6_READER dytran
|
2010-05-12 13:27:55 +00:00
|
|
|
|
|
|
|
|
Thus, you can use your reader in the same way. If you provided "mydata",
|
|
|
|
|
change ENSIGHT6_READER to:
|
2013-07-18 01:02:34 +00:00
|
|
|
|
2010-05-12 13:27:55 +00:00
|
|
|
setenv ENSIGHT6_READER mydata
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
For your information, EnSight makes sure that the appropriate library
|
|
|
|
|
environment variable is set for your machine architecture. You do not
|
|
|
|
|
have to deal with this if you locate your library as outlined above.
|
|
|
|
|
The library environment variables used are:
|
|
|
|
|
|
|
|
|
|
Machine type Environment variable to set
|
|
|
|
|
------------ ---------------------------
|
|
|

|
|
hp SHLIB_PATH
|
|
|
|
|
ibm LIBPATH
|
|
|
|
|
|
|
|
|
|
IMPORTANT: Unless the shared library is available in the
|
|
|
|
|
.../$ENSIGHT6_READER directory, EnSight will not run.
|
|
|
|
|
|
|
|
|
|
As always, EnSight support is available if you need it.

the various library routines. The detailed specifications below have assumed
|
|
|
|
|
the following are available. (Their names describe their purpose, and they

|
|
|
|
|
|
|
|
Description:
|
|
|
|
|
-----------
|
|
|
|
|
This routine is called during the EnSight archive process. You can
|
|
|
|
|
use it to save or restore info relating to your user defined reader.
|
|
|
|
|
|
|
|
|
|
Specification:
|
|
|
|
|
-------------
|
|
|
|
|
int USERD_bkup(FILE *archive_file,
|
|
|
|
|
int backup_type)
|
|
|
|
|
|
|
|
|
|
Returns:
|
|
|
|
|
-------
|
|
|
|
|
Z_OK if successful
|
|
|
|
|
Z_ERR if not successful
|
|
|
|
|
|
|
|
|
|
Arguments:
|
|
|
|
|
---------
|
|
|
|
|
(IN) archive_file = The archive file pointer
|
|
|
|
|

|
|
|
|
|
Z_REST_ARCHIVE for restoring archive
|
|
|
|
|
|
|
|
|
|
Notes:
|
|
|
|
|
-----
|
|
|
|
|
* Since EnSight's archive file is saved in binary form, you should
|
|
|
|
|
also do any writing to it or reading from it in binary.
|
|
|
|
|
|
|
|
|
|
* You should archive any variables, which will be needed for
|
|
|
|
|
future operations, that will not be read or computed again
|
|
|
|
|
before they will be needed. These are typically global
|
|
|
|
|
variables.
|
|
|
|
|
|
|
|
|
|
* Make sure that the number of bytes that you write on a save and
|
|
|
|
|
the number of bytes that you read on a restore are identical!!
|
|
|
|
|
|
|
|
|
|
* If any of the variables you save are allocated arrays, you must
|
|
|
|
|
do the allocations before restoring into them.

For unstructured parts, you can read them from your file if
|
|
|
|
|
available, or can assign them, etc. They need to be unique
|
|
|
|
|
per part, and are often unique per model.
|
|
|
|
|
|
|
|
|
|
USERD_get_element_ids_for_part is used to obtain the ids,
|
|
|
|
|
on a part by part basis, if TRUE status is returned here.
|
|
|
|
|
|
|
|
|
|
For structured parts, EnSight will assign ids if you return a

* Node ids are needed in order to do any node querying, or node
|
|
|
|
|
labeling on-screen within EnSight.
|
|
|
|
|
|
|
|
|
|
For unstructured parts, you can read them from your file if
|
|
|
|
|
available, or can assign them, etc. They need to be unique
|
|
|
|
|
per part, and are often unique per model. The must also be
|
|
|
|
|
positive numbers greater than zero.
|
|
|
|
|
|
|
|
|
|
USERD_get_global_node_ids is used to obtain the ids, if the
|
|
|
|
|
status returned here is TRUE.
|
|
|
|
|
|
|
|
|
|
Also be aware that if you say node labels are available,
|
|
|
|
|
the connectivity of elements must be according to these
|
|
|
|
|
node ids.
|
|
|
|
|
|
|
|
|
|
For structured parts, EnSight will assign ids if you return a
|
|
|
|
|
status of TRUE here. You cannot assign them yourself!!

|
must be in terms of the node ids. If you do not

|
* If going to have to read down through the parts in order to

know how many, you may want to build a table of pointers to

|
the various parts, so you can easily get to particular parts in
|
|
|
|
|
later processes. If you can simply read the number of parts
|
|

at the head of the file, then you would probably not build the

|
table at this time.

Notes:
|
|
|
|
|
-----
|
|
|
|
|
* Since you must manage everything from the input that is entered in
|
|
|
|
|
these data dialog fields, this is an important routine!
|
|
|
|
|
|
|
|
|
|
* It may be that you will need to have an executive type file that contains
|
|
|
|
|
info and other filenames within it, like EnSight6's case file.
