How to apply radial force to actor

I have a simple enemy. I can throw grenade and create radial force. Problem is that this radial force ignores character.

I found that the solution is to apply physic to the skeleton mesh. But as soon as I apply physic to my skeleton mesh, the character cannot stand, because it falls down to the ground.

Character:

Character with physic on (can’t stand :smiley: ):

Radial force just spawned and fired.

What is the correct way?

Note: The radial force is applied to the player character without any problems.

Thank you.
