      I was trying to do a drop test simulation in workbench explicit dynamics, I saw a few videos on it, but still, I couldn't get the results. I have attached the snapshots of the simulation.

      Calculate the impact velocity from the drop height using the equation or an online calculator https://calculator.academy/impact-velocity-calculator/ using the units in your model.

      In CAD, move the sphere so it is tangent to the panel.

      In Mechanical, insert an Initial Velocity under the Initial Conditions folder and assign the impact velocity to the sphere body.

      Under Analysis Settings, Output Controls, increase the number of output frames from the default of 20 to 200 so you can see the details of the sphere flexing the panel.
