This might be one of the reasons for the observed decrement. Please have a look at this discussion on how these coefficients are calculated - https://forum.ansys.com/discussion/654/material-damping-and-modal-analysis.nAlso check out the help documentation for details regarding damping coefficients 14.3. Damping Matrices (ansys.com)nnRegards,nIshan.nhttps://forum.ansys.com/discussion/3978/how-to-access-the-ansys-online-helpnViewing 1 reply thread
