How to color particles with stripes?

Using SimScale Post-processing
1

Hi SimScale,

I have a particle analysis which I am post-processing in ParaView. I would like to color particles with stripes.

These could be black and white, as in this animation:

or colored, as in this animation:

Does anybody know how this is done?

Hi @BenLewis,
Assuming that the results come from our platform, the particles themselves will contain an ID attached as a field:

Now, that will make sure your particles receive their colour based on the ID. To obtain a band separation, you need to configure the colour mapping, so that the colour space contains a smaller number, by changing “Number of Table Values” in the panel to the right. In my example I chose 8:

Here it is at a later time-step:

Hope this helps and could answer your question.

Hey @bdaqui!

Great! looks good. But can we do it without id’s information? because I think we can’t control id’s of the particles or can we?

I will look into that.

Hi @BenLewis @ahmedhussain18,
you can use a calculator filter to create a field depending on the initial coordinates and then color by this field.

Thanks everyone for your help. I intend to make a calculator filter.
