hello there. I'm trying to simulate the impact of a pendulum on my sample in an elastoplastic area and my sample is deformable and consists of skin and flesh. moreover, I consider my impactor's movement as a transitional in one direction. my problem is when I consider an impactor as a discrete rigid body, it gives neither stress values nor contour, but when I consider it as a deformable body it just gives me stress value but no contour. what should i do to get stress value and it's contour
