Bravo Bruno!
it works fine now.but I have trouble with saving it.when I save state and exit from paraView and then start it and use load state another file with the same name appear in biltin part in paraView and filds became disappear! and doesn't work correctly.

Before opening ParaView, run:

Code:

paraFoam -touch

Hi Bruno
this type of error occurs again when save and load state:

Hi Ehsan,

Sorry, apparently last night I was a bit tired already and I didn't notice that I wrote "-builtin" instead of "-touch". I've corrected the previous post.

OK, to avoid future problems with the state files, I suggest that you follow this procedure:

On each one of your cases, create 2 dummy files, one for each type of plug-in:

Code:

touch case.foam touch case.OpenFOAM

The name itself doesn't matter much, what matters is the extension (".foam" or ".OpenFOAM") and that the name is the same for all of your cases.
Instead of running paraFoam, run paraview:

Code:

paraview
Now, open the file you want to use in ParaView, either "case.foam" or "case.OpenFOAM".
Then configure things to your needs, such as: which fields to load, scales, legends, colours and so on.
Now, before saving the state file, make sure that you are at the time instance "0".
Save the state file inside the case folder.
You can now repeat the same for the other file, namely "case.foam" or "case.OpenFOAM".
Once you have the desired state files well saved, you should always use the paraview command to start ParaView and to have the "case.*" and state files inside each case.
- Keep in mind that when a state file is opened, it's hard-coded to open the case file located at the full path, not the relative path. The reason why I say that you should save the state file inside the respective case, is to make it a bit easier to locate the "case.*" files.
- With this methodology, you should be able to re-use the same state file and "case.*" files on any case.

Best regards,
Bruno

why when paraview is making images for animation,it abruptly closes itself and making animations discontinues?

what does this error(warning) means? :mad::(

when above error is shown,the maximums in images are saved wrong,
in attachments KE.0116.jpg is saved by the python script and 116 is screenshot.
----------------------------------
then troubles are these:
1) paraFoam doesn't act good with extremes of variables,means legends are in 0,1 region
2)because of 1,I open cases by paraview -dr as dear Bruno mentioned somewhere,
3)in one case,when it reaches to a middle time,paraview suddenly closes (during saving animation),
4)in other case,paraview doesn't save correct values in ranges for maximum in saving animation

That seems to be related to this: http://www.cfd-online.com/Forums/ope...animation.html
Use the command top in a new terminal, to confirm if the memory occupied by ParaView keeps rising. Or use "System Tools -> System Monitor" instead of top.

I guess it's because you didn't configure properly the script used for updating the ranges. But since you didn't give a proper description of what you've done to get that error, I can only guess.

3) Explained in the first paragraph of this post I'm writing.

4) Uh... the answer after the 2nd quote?

Best regards,

it only occupies 50% of memory but closes abruptly.

I did what you had told :(

--------------

forgot to attach system Monitor.

But how exactly did the memory occupancy by ParaView evolve along the animation?

And no, you didn't attach the image of the System Monitor :(

forgot to attach system Monitor.

Bruno something occupies the memory when paraview's are closed!
how can find out what it is?
it hardly attaches.

Have you looked in the "Processes" tab on the "System Monitor"?

a corrupted pidgin run had occupied the memory.

dear Bruno Hi,
I added this code according to what you said and I had done before also,

Code:

from paraview.simple import *



def start_cue(self): pass



def tick(self):

    source = FindSource("WR_4.OpenFOAM")

    #This works on ParaView 4.0.1

    source.UpdatePipeline(self.GetAnimationTime())



    #This works on ParaView 3.12.0

    #source.UpdatePipeline(GetAnimationScene().TimeKeeper.Time)

    



    #The array and number of components

    #arrayName = "p"

    #arrayComponents = 1

    #component = -1

    #options for component: -1, 0, 1 and 2 => Mag, X, Y, Z



    # If it's a scalar field

    arrayName = "p"

    arrayComponents = 1

    component = 0



    #Get the look-up table for this array

    lookupTable = GetLookupTableForArray(arrayName, arrayComponents)



    #get the access to the cellData or pointData

    #data = source.GetCellDataInformation()

    data = source.GetPointDataInformation()



    #get the array and the respective min-max

    array = data.GetArray(arrayName)

    dataRange = array.GetRange(component)



    lookupTable.LockScalarRange = 1



    #Now let's hack in the range values

    lookupTable.RGBPoints[0] = dataRange[0] #min

    lookupTable.RGBPoints[4] = dataRange[1] #max





def end_cue(self): pass

but this is the error:

you know that I now use 4.0.1 version,is there any other changes other than what you mentioned in post #6 I have to do to solve the issue?

Hi Ehsan,

Is the case file actually named "WR_4.OpenFOAM"? Because that error message implies that it is not.

Best regards,
Bruno

no its name is case.foam,I'm mixed up with names!
is the folder name important too?
I have to make a file with name: case.foam and open it after running "paraFoam4"?

The name and folder are not relevant to this filter. All that matters is the name you gave to it in the "Pipeline Browser" (yes, you can rename the entries there as well!).

This is because this instruction:

Code:

FindSource("WR_4.OpenFOAM")

searches the items on said "Pipeline Browser" for the name indicated.

Bruno I made a file named case.foam in the case folder and used paraFoam4 command as you said me,copy the python code and take animations but the maximums are not correct,they don't match to real local maximum values and another issue is that again " Automatic Color scaling" doesn't work and scale bar doesn't change :( :mad:

Bruno I closed that and open a new paraview and rescaling problem is resolved,I worry if I add the python code it occurs again! it was working fine before,why it has became so?
