For studies involving structural analysis of PCBs, it is typical to assume some dependency of damping to frequency (i.e ref.: Steinberg), specifically viscous damping coeficient being inversely proportional to square root of frequency (as shown in attached image). While damping coefficients can be edited manually in Response Simulation, doing that for a system analysis involving lot of modes is not practical. Is there readily available an NX Open script to automate that ? i.e script that reads all modal frequencies in the solution file and then automatically populates damping coefficients in the response simulation view.
Along the same lines, is there a depository among knowledge bases where all automation tools like NX Open scripts available to customers are stored (along with some descriptions in scope and how to use it)
Solved! Go to Solution.
See attached. It will read viscous and hysteretic damping values from a csv table and apply them to the modes in a response simulation.
The PLM World web site hosted one for years. When they decided to shut down their forum, the repository was lost as well.
Siemens PLM is working on adding a repository to this community site, but it is not yet in place.
Just had a go at testing the offered script and I get an error msg – No coded in UNF-8 format- when trying to launch the .dll
Is there a way around that?
full error msg is: The file is not encoded in valid UTF-8 and contains some characters that are not in the locale character set
