What is the preferred method for doing a smeared weight distribution in Pro/Mechanica. Here is the situation I'm trying to do:
In the process of learning Mechanica, I"m trying to replicate the results in a book on vibration analysis by Steinberg. Steinberg is calculating the dynamic bending stress in a 1.0 lb printed circuit board that is 7.0 x 8.0 x .062 in. thick. I won't get in to any of the other details, but I'd like to apply a 1.0 lb smear mass to the card. If I apply the material density, then the weight is maybe .3 lbs at most. I'm open to suggestions, so feel free to offer your opinion. My thought was to apply a .7 lb weighted link, with it coupled with the .3lbs of the bare board, would give me the 1.0 lb mass. Other question, how to do the weighted link? I applied a mass to a datum point, then did a weighted link, generated my mesh and errored out on the analysis due to the mass not being attached on any elements. Please help.
Thanks,
Randall
