### Getting the Underfull \hbox error

Hello, I have been getting the "Underfull \hbox (badness 10000) in paragraph at lines 58--61" in the following code which is the lines 57-62. Weird thing is that it worked a while ago but for some reason it doesn't work now!

\begin{equation}E^{(n)}_{\alpha,\beta}(y)=\sum_{j=0}^{\infty}\frac{(j+n)!y^j}{j!\Gamma(\alpha(j+n)+\beta)}\end{equation}\end{large}\newline Then some other functions have been defined to further simplify the solution. Afterwards various plots of different results have been obtained and drawn. The article mainly discusses influence of the $\zeta$ and $\alpha$ parameters on the evolution of the temperature field. It is finally concluded that as the time progresses, the temperature values oscillate and decay until they reach zero, and also by increasing the value of $\alpha$, the amplitude of the temperatures increases and the temperature decays more slowly. Also it's interpreted from the presented figures that decreasing the value of $\zeta$ causes the value of maximum temperature in a fixed time in the middle of the spatial domain but only for the lower values of $\alpha$, e.g. $\alpha=1.0$. The results have been mainly discussed with a value of $j=1$ which mainly affects the frequency of the temperature oscillation in the $x$ domain, meaning that with a change in the value of $j$ we can expect more oscillation in the spatial domain by increasing $x$. Also varying values of $j$ can change the rate at which the temperature decays to zero. As $j$ increases the frequency of the temperature oscillation relative to time at a specific point in the spatial domain also increases, but the time needed for the damping to occur (the time required for the temperature to decay and reach zero) decreases, which means the temperature fluctuates harder but decays faster.\begin{large}\begin{bf}

Welcome, you should stop for a while and read an introduction. Many things in your code are wrong.
The warning you get is due to the wrong use of \newline.
The smart way: Calm down and take a deep breath, read posts and provided links attentively, try to understand and ask if necessary.

Hello and thanks for your reply. I changed many many things in the code and the error is still the same. \newline isn't producing the error. I have used a similar structure to this one in some other part of the code and haven't gotten any errors.

Welcome to the forum!

I don't get that message with this code when I tested it. Can you post a code, that actually brings that error/warning message, when it's compiled?
