Applying gravitational forces?

I'm having a bit of a problem with the following (sorry, I'm rather new to HyperMesh..):

How do I apply gravitational forces to a model, i.e. how do I tell HyperMesh to use the weight of the components as a force? I created a load collector and assigned GRAV as card image, adding the acceleration value, but don't know how to effectively 'activate' the force (I'm assuming it should somehow be displayed)...

I would be very grateful for help!

you have already done it, just solve and see the results, your element masses will be multipled by the defined acceleration field and forces will have been calculated and applied then.

Thanks a lot for replying, I realized later that it was already working, I was sort of waiting for the load to be shown in the model...
