I need help in simulating the lifting of modular spreader beam.
Good day everyone,
I would need some help in simulating the lifting of the modular spreader beam as follows in the Nastran environment;
I have tried the method as listed in the link and using the similar constraint setup. here: https://www.autodesk.com/support/technical/article/caas/sfdcarticles/sfdcarticles/How-to-perform-ana...
But it would still not work and keep giving me the Fatal Error E5004.
This is not a problem when I tried to simulate a normal solid spreader bar suspended by 2 slings at the top towards the point of lift or hook. The only difference between this modular spreader beam and regular spreader beam is the number of suspension points towards the crane hook.
I have tried to change the sling connectors from Rod, Spring, Cable and Rigid Body, all will result to the same Fatal Error E5004. I have also tried to change the mesh, going from the biggest to the smallest mesh allowed. Nothing still works.
Any advise will be greatly appreciated. I have attached the files here for you to see what I did wrong. I have to split the archive and post it as a reply to this message because of the file size limit per file. The archives need to be downloaded into a same folder to unpack.
Thank you.
