Unrealistic mass using masscalc
Hello everyone,
I'm working on a project which consists of a carbon fiber truss structure (.hm file annexed below) and, even though I've got the right material properties inputed, the result mass is nearing 480kg for a 1m tall trussed structure. I've cheched my units and it's consistent all over the board (MMTS system).
I have no idea what can be causing that, can anyone help?

Hi,
Why it's unrealistic ? do you have experimental measurement?

Carbon fiber truss with 'solid circle' section?

My understanding of unrealistic comes from past experience from working with those carbon fibre tubes/rods. I don't think that a 1m tall trussed structure could have a mass of 480kg as OptiStruct says. Nonetheless, I might be commiting an error somewhere and not seeing it, so that's why I asked.

Yes, I'm using rod elements to validate my structure. Does it change something? Even with rods it shouldn't be that heavy...

Turns out I was doing basic math wrong. Sorry for the inconvenience, guys!

Alright. Good luck.
