<div dir="ltr"><div>Hi Nitish,</div><div><br></div><div>You're modeling your Aluminum sphere as a solid density, gaseous fluid. There are no additional physics built into FLASH related to the low-temperature covalent bonds, etc. that hold together a liquid or a solid -- it might be worth considering adding those physics in the future! For now, one trick that we do when handling room-temperature solids is to numerically "freeze" the cells in place until they heat to a certain temperature. If you're interested in that, it's is something that can be done by declaring the BDRY variable in your Config file, and then writing a script to dynamically set and unset the BDRY variable (between 0 and 1) in Simulation_adjustEvolution.F90.<br></div><div><br></div><div>Scott</div><div><br></div><div>Scott Feister</div><div>Assistant Professor, Computer Science</div><div>California State University Channel Islands<br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, Nov 5, 2019 at 9:49 AM Acharya, Nitish <<a href="mailto:nachary2@ur.rochester.edu">nachary2@ur.rochester.edu</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

I am currently working on a simulation based on LaserSlab in FLASH. I have a small Aluminum sphere inside the target material. Initial density and temperature for the Aluminum sphere is set to solid density value and room temperature. I would like to know here,
does FLASH actually simulate solids? Or is it treating the Aluminum sphere as a fluid?</div>
