I can't apply the same force for two different bodies
I am designing a lightweight concrete composite brick which is infilled with different material in the middle. The infilled parts are different bodies. When I apply force to the brick only the brick gets deformed meanwhile the other infilled bodies are not deformed. How can I make them to deform under a force applied in the y-axis?
The results are the same even if i use the same materials for all the bodies. I have attached a simulation video for better clarification
