<em> [NEWS] 04.10.23 </em>
- laine is using a new numerical solver (C++).
If you experience any bugs, please report it <a
target="_blank"
rel="noopener"
href="https://github.com/srnogueira/laine/issues"
>here (github)</a

<p>
<em> [UPDATE] 04.10.23 </em>
- included functions for Rayleigh flow
</p>
<hr>
<p>
laine can solve <em>nonlinear systems of equations</em> in a easy
way. Just input your equations and press <em>Solve (F2)</em>:
</p>
<p>$$\text{In math: }x^2+x=3$$ $$\text{In laine: x^2+x=3}$$</p>
<p>
You can also use <em>Functions</em> to input thermodynamic
properties in your problem. If you need more details read the
