How to set up animation in Paraview?

[Sony Achmad Louis]

Hello gprMax,

Thanks for guiding me recently,

I want to ask a question.

How to set up paraview to display #snapshot animation seems like example video on youtube?

I couldn't display EM wave propagation in animation (see picture).

I will be grateful if you give me guidance to solve it

Hi Sony,

Have you followed the guidance in the documentation - http://docs.gprmax.com/en/latest/output.html#snapshots ?

From your screenshot you seem to be trying to visualise the receivers (shows the location of receivers) from your geometry file. You need to select the snapshots in the Pipeline Browser and them choose the field you want to visualise.

Thank you for replying my message, Mr. Craig.
It's really helpful.

I tried to follow the guidance in the documentation.
I selected the snapshot as shown in picture 1, and choosed E-field -> Z -> Surface.
And I run the animation, but the geometry of object no displayed.



Then, I opened geometry file (.vti) of snapshot as shown in picture 2.
The visualization of #snapshot looks correct, but the scale of color legend is false when I compared to Ez data from matlab.



Any suggestion what supposed I do to solve it?
Because I have no much experience of using Paraview.

As you have realised the geometry file and the snapshots of the EM fields are separate. You can overlay them in Paraview as you have done in the 2nd image. You'll need to open the Color Map Editor (View menu) and experiment with the colour scaling to suit what you want to visualise in the snapshots. Have a look at the tips in the docs link from my previous message.

Paraview is a powerful visualiser for scientific data and there is lots of info on using it on the web.

Kind regards,

Craig
