Paraview

[ibry]

Hello everyone,

How can I use the paraview?
And I also don't know to open *.vtu, what is the software to open it?
Thank you.

For FEAP, you will need to use a macro, see here, http://feap.berkeley.edu/forum/index.php?topic=1068.0

Sure, I used macro for paraview.
I just don't know how to open file *.vtu.
Thank you.

[Prof. R.L. Taylor]

You should not need to open the *.vtu file.  It is to be read by the Paraview program (which you must download from their web site)

Sorry I ask the common question.
How can I read pview command in the input file, if I want to plot at time 4 seconds (for example)?
I just write 'pvie,time,4' or how? Because I didn't get the expected plot result.
Thank you.

[Prof. R.L. Taylor]

YOU can run your solution to time = 4, then plot with pview.

The commands to run to time = 4 are

LOOP,,10000 (bit enought to get to time 4 - it does not have to be 10000)
  TIME,,4
  LOOP,,newton_its
      TANG,,1
  NEXT
NEXT
PVIEW

Dear Prof. Taylor,

should command be PVIEW or PVIEW, time for this case?

Thank you very much in advance for your answer!

[Prof. R.L. Taylor]

If you only want one file then it should not need the 'time', if you are going to output multiple files you should use the 'time' parameter.   For example if you were to output every 10 time steps with a dt= 0.4 you could use the commands:

       dt,,0.4
       loop,,20
          loop,,10
             time
             loop,,10
               tang,,1
             next
          next
          pview time
       next

This does 200 time steps but only writes the paraview output every t0 time steps (i.e., at times 4,6,12,16,....

Dear Prof. Taylor,
thank you very much for a detailed description of this command PVIEw!

I am not sure you have the latest macro can you post what you have so I can confirm the version
