I am running the LaserSlab simulation with a target, two foils, and a support to hold the foils (shown below). I also added the propaceos patch to read my propaceos EOS and Opacity tables; however, when I run the program with these files, I receive the following
error after a while:</div>

From what I can see the output looks the same on visit, but I would still like to have all parts of the simulation converge if possible. If anyone else had encountered this issue before any help would be appreciated. </div>

Also, in the flash.par file, I am using the same propaceos file for all of my materials in both the EOS and Opacity sections because I am just testing if it works. <br>
