fluent results streamline problem

bjorson · October 6, 2013, 13:34

Hello, i am new in ansys fluent and I have problem with streamline. As you can see in this image, streamline are generated in small part of my model, but I want streamline in whole model. My streamline starts from inlet.

Do you have any suggestions what is wrong with it, why my streamlines don´t continue through all model?

Thank you a lot.

Hi, do you mean step tolerance in limits options? I don´t get you. Where can I change steps, you talked about?

Thanks

(sorry, i am really new in fluent)

Just Steps in Pathlines Options. Change it from 500 to for example 5000.

Hi,

I am having a problem with my model where the streamlines do not go all the way till the end and got stuck as soon as it hits the wall. It just doesn't spread away as it is supposed to.

The issue is with the post-processing only. Because in Fluent solver itself, the pathlines seemingly work just fine.

Any suggestions or ideas?

Kind regards.
