Everytime I tried to run a simulation, I keep getting this message "material is not defined for one or more components." I've created two new custom materials: normal weight concrete (150 pcf) and insulation I've created just regular blocks and did a thermal simulation using the new materials I've introduced. Everything ran smoothly; however, in my actual model I cannot run a thermal analysis. I've also tried to alter all the parts with solidworks material and I get the same problem.
I'm using SolidWorks 2011 so if you plan on editing my model, please save it in a 2011 compatible version.
Please help!! Thank you!
