Force Reaction Ansys LSDYNA

      Hi, I'm doing a simulation and test validation for impact force plate. The problem now is that, the reaction force from simulation is not the same as the test. I want to know if I am modelling the force correctly. Picture below is the location of the sensor, in the model I make it as fix support, then I use it to capture the force reaction at Z-direction. In actual test, that is the location of the force sensor. Am I model it correctly or is there any other wat?

      Could you please provide more information by adding more images.

      1. Please show an image with the coordinate system. Which direction represents the z-direction?
      2. How are the boundary and initial conditions applied? Show an image with the scopes of the boundary/initial conditions, and describe them.
      3. What is the force reaction value you obtain from the simulation and what value is obtained in the physical test?
