Hi William,<br />
<br />
I cannot reply to your last post, but to close this issue from my side just a comment that obviously FE mesh density and SnS resolution is to be chosen carefully.<br />
<br />
I am glad that you have found the time to check the model and I agree that SnS is without discussion the faster way to do it.<br />
<br />
Cheers

Hi<br />
<br />
Here are the results using S&S and ANSYS. My displacement contours appear to be slightly different to yours although the maximum amplitude is about the same.<br />
<br />
In S&S I have used the lowest resolution setting and in ANSYS I have used about 30K element. The percentage difference between ANSYS and S&S is about 6% (displacement) and 10% (stress) for the current mesh setting. However, the effort involved in setting up within ANSYS is considerably greater (about 500%) compared to…

No problems with the IGES file, I will post it a bit later with the other data (loads and restraints).<br />
<br />
Sure, the Straus models may be not perfect. It has approx. 74.000 bricks and is cleaned up several times to erase all of the microscopic elements. This was the smallest amount of bricks to get "round" holes and fillets without any specific time consuming mesh refinements.<br />

Was wondering whether (providing it does not present any confidentiality or IPR issues) you could post the geometry as an IGES or STEP file and I can then run the same problem using ANSYS. We can then do a tri-FE comparison.<br />
<br />
One thing I noticed was the stress contours from the Straus7 analysis contain sharp discontinuities which would suggest that some mesh refinement might be required.

Thanks for the response!<br />
<br />
I was also thinking about this matter and came to the conclusion that the stress peaks are something that is really not relevant for the overall picture of the analyzed part. In most cases those few peaks have to be hidden to see the overall picture of the part (not just a blue painted part with two red dots). This gave me an idea for the "wish list" - to have two sliders at the results bar which would define the range of results we want to see.<br />

Anyway, SnS is really amazing and I fully respect the huge amount of work put into it! I will post some more examples, also with gravity.
