• Added mass for bouyancy in Dynamic Analysis

    Hi everyone, Could someone explain me how SACS consider bouyancy mass their dynamic analysis? In Dynpac tutorial (§2.3.1), it said "For structures immersed in fluid, the added or virtual mass and the mass of entrapped fluid ca nbe generated automatically…
  • SACS - Rotational Mass Participation Factor

    Dear Bentley, Do we have any ways to get the Mass Participation Factor for Rotational Degree of Freedom? The mass participation report shown in Dynlst is only reported for Translational Degree of Freedom only. Please help to suggest Regards …
  • Selection of Retained DOF nodes

    I have read through the Dynpac Manual Section 2.1 on Retained Degrees of Freedom. I understand that Dynpac uses a set of master (retained) degrees of freedom, selected by the user, to extract the Eigen values (periods) and Eigen vectors (mode shapes)…
  • Dynpac module (to estimate natural period) & Gap elements with initial gap

    Can Dynpac module (to estimate natural period) capture the initial gap of say 50mm incorporated in the model.. any thoughts..? or is it only limited to the static runs. Thanks
  • Selecting modes with mode number higher than 100 for steady state deterministic wave analysis

    Good day, I am trying to determine the steady state response of a large model loaded by waves and current. Due to the size of the structure and the number of dofs to be considered for dynamic analysis, the number of structural eigenmodes is far…
