I have no idea what the default parameters in the database are. Did you change the latent heat to meet the actual material you are using? Again, I always found it very informative to have a surface with and without PCM side by side and look at the surface and / or central node temperatures of the layer in question. Did you do that? From these temperatures you can also estimate if you are actually melting / solidifying the PCM as Monika mentioned.</div><div><br></div><div>Are you using h3k output? If not, it may be an additional idea. You should find a variable "PCMFAC" in the dictionary. This, I think, is a factor which is 0 for solid and 1 for liquid (or the other way around) and thus gives direct information on what is happening with the PCM.</div><div><br></div><div>Best</div><div>Achim</div><div><br></div><div><br><div><div>On Sep 11, 2014, at 7:53 PM, Arianna Sdei <<a href="mailto:A.Sdei@brighton.ac.uk">A.Sdei@brighton.ac.uk</a>> wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><div lang="EN-GB" link="blue" vlink="purple" style="font-family: Helvetica; font-size: medium; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: -webkit-auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; "><div class="WordSection1" style="page: WordSection1; "><div style="margin: 0cm 0cm 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif; "><span style="font-size: 11pt; font-family: Calibri, sans-serif; color: rgb(31, 73, 125); ">Hi Achim,<o:p></o:p></span></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif; "><span style="font-size: 11pt; font-family: Calibri, sans-serif; color: rgb(31, 73, 125); ">I am using phase change plasterboard via the active material database and I am using quite a bit of it.
