Hi, Does anyone have experience with modeling hotplates or using the ETherm module in MEM CAD? I am trying to model some hotplates with meander type heaters and holes in them. The problem is that I keep getting temps that are below the ambient temp that is set in a convection-radiation boundary condition on the top and bottom of the plate. The problem seems to occur between the metal heater and the holes in a nitride support layer. Unfortunately, Coventor has NOT been too helpful so far. Thanks, Mike
