[OpenFOAM] Visualizing two fields

cute · June 4, 2016, 20:02

Hi there,

I have two field values that I want to visualize at the same time. Say I have fields X and Y, how can I run animation to see both at the same time in paraView?

Any idea and suggestion or comment?

Thanks.

Hi cute,

you can define a new custom filter in paraView.

When you define a new custom filter you can show any field in first filter

and another field in second filter and ... .

Thanks rapierrz for the reply.

What filter should I need to use. I am new and still learning.

So far I tried to load data two times in pipeline and used translate option to translate shapes. It works with surface plot but does not work with volume.

I have my 3D data in VTK format. When I load it, I visualize it with volume option (not surface). If you can elaborate more, that will be helpful.

Thanks.
