I am modeling the parts in Solidworks and converting them into .step and then importing into ANSYS for simulation. Theoretically, the total energy of the system should be equal to 1\/2mv^2 as i have a moving part collide with a fixed position part.&nbsp;<br \/>Moving Part: <img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/01\/24-01-2024-1706094677-mceclip0.png\"> &nbsp;<br \/>Stationary Part: <img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/01\/24-01-2024-1706094964-mceclip1.png\"><br \/>Ansys says the mass of the moving object is 0.915kg and the object has an initial velocity of 6m\/s. Combined they equal 5.5147J of energy. However, plugging the mass and the velocity into 1\/2mv^2 yields 16.483J. My question is where am I going wrong and why is there such a large discrepency? I should also mention that I mated the parts so that they are touching. As far as I know, they are still 2 distinct parts.<br \/>Even if the answer isn&#8217;t found, I would at the least like a plausible explanation of the issue.
