Re: [Paraview] PV 3.6.2 and VisIt Plugin: crash when loading state with Tecplot files

2010-01-27 Thread Richard GRENON 

Hi Dave and Burlen

Another Test loading state for a Tecplot file that contains two zones works!

- Read two zones Tecplot File
- Extract Block 1
 | Extract subset 1 from Block 1
   - Color Subset 1
- Extract Block 2
 | Extract subset 2 from Block 2
   - Color Subset 2

Another Test loading state for a Tecplot file that contains only one 
zone crashes PV.

- Read single zone Tecplot File
- Extract subset
- Color Subset

A final Test loading state for a Tecplot file that contains only one 
zone and using "Group datasets" filter works!

- Read single zone Tecplot File
- Group datasets
- Extract subset
- Color Subset

So the problem happens only when reading single zone Tecplot files. The 
work around is always to use the "Group datasets" filter after reading, 
even if there is only one file! No problem occurs when reading a 
multi-zone Tecplot file.


Best regards.

Hi Burlen.

Thank you for this answer.
Working with state files (as we do with layout files with the Tecplot 
software) is essential when you have big pipelines. Imagine you spend 
one hour to build a big CFD pipeline... and you have to rebuild it 
each time you want to analyze new data! Really, it would be helpful if 
you could fix this problem in a future release. And also, it would be 
fine if the state file could save what arrays are selected in the 
Tecplot Reader (no array is selected when loading state, but is it a 
PV problem or a VisIt problem ?).


The work around with the actual release is to use the "Group datasets" 
filter to build a new dataset from the Tecplot readers. At least, it 
works with single zone Tecplot files, but I will make other tests with 
multi-zone Tecplot files.


PS: I discovered another bug. PV crashes when loading state (with work 
around) referencing Tecplot files if the Tecplot files are not found!


Best regards.

Hi Richard and Dave,

I think that the way the VisIt plugin currently communicates 
information between client and server is not going to work with state.


The way it is now the plugin repeatedly sends variable length vectors 
of array,block,material ids,, etc one array for each mesh. Each of 
these might have a different size depending on the user's selections. 
In order to work around the fact that PV sm vector props don't support 
variable length vectors it also expects the array of mesh ids to be 
sent first, from this it sizes the other arrays to fit what will be 
incoming.


One solution would be to serialize the users selections in a single 
string, using sm string vector property to send server side. That 
would work with state. Otherwise I'm afraid your going to have to do 
some heavy sm programming.


I regret the way I did that, if it's helpful I'll volunteer to fix it.

Saving state of this pipeline, the pvsm file can be used.
Note: After loading the pvsm file, you must go on the reader of
each tecplot file, select the arrays (unselected by default), then
click apply.

Of course, I can attach the two corresponding pvsm files if it may
help.

Re: [Paraview] PV 3.6.2 and VisIt Plugin: crash when loading state with Tecplot files

2010-01-26 Thread Richard GRENON 

Hi Dave.

I attached a tar gzipped file that contains the two pvsm files:
essaipv01.pvsm : state file of Test 1, crashes PV.
essaipv02.pvsm : state file of Test 2, OK.

I can't send my two formatted Tecplot files (too big) but I think you 
can easily rebuild them with any data from the headers below.

Each file is a formatted Tecplot file with name ending with ".tp"
There is only one zone (block) per file.
Each zone is a 3D IJK ordered grid with coordinates x,y,z and some other 
scalar arrays (pressure, temperature, etc...)
Following are the file headers where you will find the dimensions of the 
grids and the variables:


- File 1:
TITLE = "E_Fld0001_RAPRO2_F06_M020"
VARIABLES = "x" "y" "z" "vx" "vy" "vz" "M" "p" "Pi" "rok" "viscrapp" 
"ro" "tsta" "tgen"

ZONE T="Window(s) : Dom0001",  I=181,  J=9,  K=97, F=BLOCK

-File 2:
TITLE = "E_Fld0002_RAPRO2_F06_M020"
VARIABLES = "x" "y" "z" "vx" "vy" "vz" "M" "p" "Pi" "rok" "viscrapp" 
"ro" "tsta" "tgen"

ZONE T="Window(s) : Dom0002",  I=61,  J=9,  K=25, F=BLOCK

Best regards,

Richard

[Paraview] PV 3.6.2 and VisIt Plugin: crash when loading state with Tecplot files

2010-01-26 Thread Richard GRENON 

Hello.

PV 3.6.2 crashes on Linux when loading a state file (*.pvsm) that 
references Tecplot files.


Here is my test:

-Starting PV 3.6.2 (Linux), I load the VisIt plugin.
-I open two 3D IJK ordered Tecplot files (*.tp). No problem (PV freezes 
while loading the files, but I can continue after the files are loaded).
-I extract the J=1 surface for each file, I group the two extracted 
surface and I color this new dataset with one variable.

-I save the state of my work in a *.pvsm file.
-I disconnect to clear all data.
-I try to load the saved pvsm file. PV freezes as it does while opening 
Tecplot files, then it crashes!
The same crash happens when I try to load the state file after 
restarting PV and reloading the VisIt plugin.


Has anyone an idea?

Best regards.
