The following work looked into sensitive analysis. Sensitive analysis is used to gather some data of analysed problem and further to reduce the time required to run a simulation. The work explains importance of the tool in field of mechanics engineering. The work briefly outline applications of the tool in industries. Also I-beam analysis was done to better understand influence of sensitive analysis. The results illustrated that by reducing nodes in the geometry of the I-beam the output values stay the same, but too much reduction will lead to incorrect results. The comparison of the two methods also took a place in this work, to see the correlations and discrepancy of the problem.
