  I'm facing an error
  Solver pivot warnings or errors have been encountered during the solution. This is usually a result of an ill-conditioned matrix possibly due to unreasonable material properties, an under-constrained model, or contact-related issues. Check results carefully.

  Hi,
  I believe your model is not properly constrained. Please watch this video.

  Since you have a Fixed Support, you probably have an error in the value of Young's modulus in Engineering Data such as putting in the MPa number when the units were set to Pa so you have an error of 1 million. Or maybe the Force is off by a lot. Check the numbers and units carefully.
  Another way to approach this is to use a Displacement instead of a Force.
