How to access particle acceleration and velocity fields?

[Guest ravin]

I want to access particle acceleration and velocity fields in an expression. How can I extract these specific attribute per particle?

thanks,

By the way, you've double-posted every single one of your questions here and on SideFX. Almost everyone here visits both of those forums so there's no need for it. You can also search both forums and will find that your questions have probably been answered already, with example files! Or check the help cards for each node (parameter window, click on the ? button); they contain a lot of useful information regarding local variables and have example files as well.

Okay I will keep that in mind to single post in either of the forum. And Ya I have been reading the help files as well but I couldn't find any example where they have used acc or vel in an expression. I am attaching a simple setup where I have one particle and a box. Now if I want to reference particle's acceleration to box's position how will I do it? If you could show me it would be gr8 help,

thanks,
