Right! I think so.<br />
I’d like discuss with you!<br />
<br />
1st,as one case ,S&S do not check the convergence automaticly, we should do it manually.<br />
<br />
2nd i think the max resolution is not necessary every time,for saving computing resources!<br />
<br />
3rd ,also the max resolution(now is 100,000 elements) is not enough.It's just ower beta release.Far more is needed in many cases.<br />
<br />

I'd like to have the functionality of batch tasks input,not only the set of solutions as you mentioned, but also the set of load-locations(10kN,15kN,20kN...),the different restrictions,a series of the product...etc.<br />
<br />
<br />
If multi-job is allowed to launched , multi-result is also allowed to take put into one sheet,<br />
we can write a .txt or a .bat file,submit it when leaving out,then we can get the results to discuss the next morning.<br />
May be we could design a plus-in for S&S ,:)<br />
<br />
Btw,<br />
How do you choose the set of solutions by now ,at 10'000, 20'000....100'000?<br />

If we only could launch a multi-job and see the results of a complete set of solutions (at 10'000, 20'000....100'000) maybe we could also discard the results with the max deviation.<br/>
<br/>
Actually I already do that, solving at different detail levels....as you know nobody can take for good a single result, even if it's at the max resolution.

Thank you ,Cristian!<br />
<br />
Your idea is nice, i think the designer or engineer may be very familiar with its own models&conditions.He can find a suitable resolutions, by solving several models.<br />
But it's not easy to the S&S . The size&shap of the models may vary greatly!Optimization of numerical algorithms must be used to choose a suitable resolutions quickly.<br />
<br />
Of course it‘s very convenient for newer.

I found Richard's example to be very clear showing the meaning of "convergence".<br/>
<br/>
It would also be a natural evolution, in SnS, to allow an automatic reiteration of the solution at different resolutions in order to calculate the convergence, or at least to show the results in a table/graph.<br/>
<br/>
Maybe a simple button to choose from the normal and the "accurate" solution?<br/>

Richard, thank you for posting this example and your study of the solution. It is a perfect example of how to validate Scan&Solve (or any other FEA) solutions. Your table and graph suggest that the max displacement solution converged to a value around 3.78E-03 and the max stress fluctuates in the range 62-65 MP.<br />
Normally, it is much easier to get convergence in displacement values, because stress varies so rapidly<br />
in the neighborhood of stress concentrations point. But looks like in your…

in the neighborhood of stress concentrations point. But looks like in your case, both displacement and stresses converged. Well done!<br />

To answer your question about the "computation box" -- it is always an integer multiple of the element size, because our "mesh" always covers the geometric shape with identical elements. So if you change the element size (or resolution), the computation box is adjusted too. Hope this answers your question.
