you need to post a pack and go of the model, only the SLDASM was sent, none of the parts that go with it so it can't be opened to check it out.
just based on the graphics, it looks like to me you should start by building a simplified rep to get your head wrapped around the beam and mixed meshing
Like I said, I have done various simulations in 2013, but never in Solidworks 2014. This is the only discrepancy I can find given I have tried many scenarios in the static simulation.
In the screenshot below:
- The fixed locations are the same material as the supports in the assembly (6061 Alloy)
- A contact set is established between the top face of the fixed locations, and the bottom face of the I-Beam
- A force of 10000 lbs / 35 ft is normal to the top face of the I-Beam (-Y direction)

If you're using solid mesh elements, it may be failing across the short edges depending on the mesh size you're using. An alternative may be to use beam elements instead of solids. This may work well if your primary interest is displacement.
All the best,

If I choose to use beam elements, the results will not differ from the results from using solid elements correct? The main thing I want to get from this study is a stress plot of the beam. More holes are going to be drilled in it which could significantly reduce it's structural integrity. I don't understand why in Solidworks 2013 I can run this simulation with no errors, but cannot generate any results in 2014. (Not a compatibility issue)
Since it is the mesh that is failing, I would start getting rid of features (ie. holes) until the part is able to mesh. That should help you narrow down what is causing the mesh to fail, and hopefully repair it.
Since you are trying to get results that include the holes in the beam, you will have to use solid elements. Using beam elements will not take the holes into account, it will just assume it is a solid beam.
so you want to use beams or solids?
Ok, I will use solid elements. So what I understand is in order to run my simulation, I have to suppress cut-extrudes in the beam. In other words, my overall goal isn't achievable through a simulation study in 2014. I did the same test to this beam in '13 about a year ago and generated the results I was after.
if you want to use beams, you need to suppress all the features because the beam is assumed to be a constant shape. like a sweep almost. (note, there are some special exceptions here but they don't apply to your case)
if you want to use solids, you can have any holes that you want in it. but only keep the ones that are important. otherwise you're wasting computational time on things that might not affect your results or that you don't care about.
i think we're missing 2 things:
1. what exactly did you do in 2013?
2. what exactly is your goal of the analysis?
there should be no difference between 2013 and 2014 if you are using the exact same model and method.
i opened the simplified version that you posted in 2014 sp4.0
first thing i looked for was a study in the sldasm, there was none
so i dug into the beam part, every element had a red X on it indicating an error
the faces for loads and restraints were missing their references
i fixed that and the model ran fine with solid elements
can you open that model, go to tools > options > system options > performance and enable verification on rebuild then go into the model and perform a CTRL-Q to see if you get the same errors?
I wasn't suggesting you suppress all of the holes permanently. Just so that you can narrow down what is causing your mesh to fail. Once you can find that, you can hopefully repair the problem, and then bring the other holes back. Hopefully whatever is causing the mesh failure isn't something that will really effect the results, and you can just leave it suppressed.
