problem with extracting data from paraview
 

Hi all
i want to save the trajectory of a stream tracer.i used save data to save it as scv file but it is too heavy to save all the data (about 7 gig) and paraview crashed during the saving scv file. but i need just the location (point0 point1 point2) and not the other data (for example i dont need the p v ..).
is there a way to save just location an not the other data in order to decrease the volume of scv file?

many thanks in advance

i have still the problem,no one could guide me about?:confused:

Hi,

You can use Pass Arrays filter to leave the unwanted data out. Is your streamline data really over 7GB in size? Can you elaborate a bit more what you're doing? Maybe there is a better way to do it.

Hi Mikko
thanks for your reply.
i have tried your suggestion but in pass array ,the options that i can choose are: :

angular velocity
integration times
Normals
Rotation
U
vorticity
P
and i just need the trajectory of streamtracer (i mean point0 point1 point2) ,but in pass array there are not,do you have another suggestion?

ps:yes,im calculating the particle trajectory for a lone time and the the data that i want save is huge(about 7 gig)

Hi Arash,

In Pass Array filter choose all variables to leave them out and then save the result as .csv. Now you should have exactly what you want, the coordinates only.

Dear Mikko

it worked.thank you so much :)
