</div>
<div>
<p class="MsoNormal"><span style="font-size:11.0pt">Dear Flash users,<br>
I downloaded the 4.8 version of FLASH, I tried to run the 2D Z-pinch <br>
example (flash_ug_2d.par) and during compiling had some errors. In the <br>
4.7.1 version, the same example runs properly. Are there any new <br>
libraries for the 4.8 version that I need to include? I am successfully <br>
running many simulations in version 4.7.1 without any issues.<br>
<br>
Thank you in advance.<br>
