Simple Model 1

[Nella95]

Simple solution - I know it. Could do it by hand in 30 minutes - maybe less. It's a simple - force applied, can structure withstand the load.

Since, I got it secondhand, I'm thinking there are some issues in the model. What are some things I need to keep an eye on?

Not quite sure what your problem is from your description.

What type of model is it?

surface
SW native

Yeah, sorry my description was so vague, but it's sooo easy, and I was neglecting to describe the problem b/c it was that easy.

Problem: 600 lb solid cube (not centered) sitting on a flat piece of steel , approximately .125 inches thick, which (that piece of steel) is resting on a rack, approximately 3/4 of an inch off the ground. This rack consists of four supports which hold up the piece of steel, and holds the rack together in a rectangular-type shape.

I'm not necessarily looking for a solution, but perhaps a method. (I've guessed that the problem isn't so much with my method, but maybe the model I inherited has a bug or two in it. But I'm open to any suggestion.)

I take it you are just concerned if the "shelf" can hold the 600lb block, right? I'd just model the shelf and use split lines on the bottom face to define where the supports are, then another split line on top to represent the 600lb block. Constrain the supports and load the "block". Should solve quickly.

MadMango - you were right on the money,

except now, I'm not sure how to demonstrate a non-linear remote load, to my model. Or, from what I've described, does that sound like a non-linear remote load, anyway?

 

[MadMango]

I don't think you have to worry about it being a non-linear load. The mass is static.

I upgraded to SolidWorks 2006, and this simple model won't work anymore. It says 'reduce the element size.' I do, then it says computer peformance may be lacking. There's not much room for element size variation in-between the two extremes.

Each newer version of SW adds more features and functionality that in turn require more computer resources. You may have to upgrade memory, video card, processor, operating system, or a combination of some or all of the above.

You should post your upgrade problem in forum559 as it is a different topic than this one.
