Understanding Mass Participation Factor Results in Frequency Studies

EmailFacebookLinkedInTwitterShare

When conducting a frequency or linear dynamics study in SOLIDWORKS Simulation, a highly recommended, best-practice post processing technique is to investigate both the Effective Mass Participation Factor (EMPF) and the Cumulative Effective Mass Participation Factor (CEMPF) of the output mode shapes. This recommendation was duly noted by my colleague Bill Reuss, in his Blog article from August 27, 2019 entitled ‘Recommendations to Achieve Accurate Results with Linear Dynamic Analysis’. SOLIDWORKS Simulation help defines EMPF as follows: “The effective mass participation […]

SOLIDWORKS 2020 What’s New – Simulation Evaluator

EmailFacebookLinkedInTwitterShare

A brand new feature introduced with the launch of SOLIDWORKS 2020 is a diagnostic tool called Simulation Evaluator. The purpose of this tool is to check the setup of a simulation study, prior to solving, to determine if the setup is correct for a successful simulation. Simulation Evaluator performs a number of system checks prior to running the study which aids the user in the successful setup of the study. It first checks conditions related to the results folder, including the storage […]

SOLIDWORKS 2020 What’s New – Free Body Forces for Nonlinear Studies

EmailFacebookLinkedInTwitterShare

A neat new feature that has been added to SOLIDWORKS 2020 is the ability to interrogate free body forces after running a nonlinear static or nonlinear dynamic study. The ability to compute and interrogate free body forces in SOLIDWORKS as part of simulation post-processing has existed for a long time but has been limited in previous versions of the software to linear static or dynamic studies. The first step in the process is to make sure the button for Compute […]
