Help with Material Properties

Question asked by Dave Branco on Jan 27, 2013

Can anyone help me out here.  I am running a steady state model with head conduction in solids.  The only material property I should need to input is thermal conductivity and in some cases that is the only material property I actually have.  When I create a new material, Solidworks is forcing me to input specific heat, density, and melting temperature but what if you don't have those values and you don't need them?  Specific heat is not needed for a steady state run and density is not needed if gravity and pressure potential are turned off so why can't we just leave those blank?  I am affraid of the following scenario: setting an arbitrary value for the properties I do not know and then in the future using that material for an analysis where those properties are actually critical, and not realizing that they were set as arbitrary values before.  Does anyone have any thought/opinions/suggestions?
