<p> <\/p><p>So you are probably right that it would work with only one mass sink (and do the rest with temperature dependant material properties), but I have to admit I didn’t build the whole model from the ground up. In fact a colleague of mine set it up in the way that there are 2 zones, one that is filled (at the start) with the intumescent in gel form (its mass is updated minus the water-vapor that leaves throgh the outlets and the mass that is generated in the other zone) and the other zone that gets filled with the foam. Even then I have highly temperature dependent values in both zones but a few things are constant, like the gel is always transperant and the foam never. However, no matter how this is realized it shouldn’t have an influence whether I can use multicore or not.<br><br>Regarding the other files, they should appear when you click on the links ….. if you aren’t permitted to click on links I wonder why we are allowed to post them. Anyway, here is the UDF:<br><br><\/p><\/p>\n
