I’ve been searching around but I wanted to see if anyone could post a really simple Ember Force setup? I tried creating a Sim Ember, create an output node, specify force, connect a simple vector value to it then finally connect Ember Force to Sim Ember but when I try to use this spacewarp with a simple particle system Max crashes. What am I missing?
Looks like a bug when using simple particle systems.
Using PFlow or MassFX, it works as expected.
For example:
*Hold SHIFT and click the SIM Ember icon to create a default box
*Open the Initial Flow, set output to Force, set input to Vector and enter 100.0 in the X component.
*With the SIM Ember object selected, click the Ember Force icon to create the space warp and automatically connect to the SIM Ember.
*Create a standard PFlow at the origin, delete the Speed operator.
*Drag a Force operator and pick the Ember Force.
Result: The PFlow particles will be accelerated along the X axis.
You can now expand on this by producing a more complex field and advect it over time if desired. The above just shows the simplest possible case.
When I created a PCloud and tried to bind it to the Ember Force SpaceWarp, Max crashed. Will log it as defect.
Ok, so my thinking wasn’t wrong then. Thank you for the explanation and reply! 
Binding a Space Warp creates a special Binding object. It is quite possible that we did not implement it correctly.
All the cases where it works right use the Force node directly in a paramblock property (Force op in PFlow and Forces list of MassFX).
I have logged it, we will see what it is…
Thanks! Normally I don’t use basic particle systems but just for testing purposes it was the quickest thing to do.
