Hello I'm trying to simulate a block material which is put in a laminar flow. What I want to study is the termodynamic of the system ( because the fluid and the material have different temperatures) and the fluiddynamic. My problem is that when I select the materials domani for the 2 blocks, one inside the other it doesn't work: in fact the bigger block made of water it's okbut the interior block whic maybe suppose now made of plastic, Comsol wanted me to know the "mu" value and force me to set it. How can I solve this problem? Thank you all, bye :)
