      Hi,

      I attempting to sun a thermal transient simulation with a shell elements. Whenever I run the simulation I get the following error:

      I can't find any where to define this property in the material properties for the body. Here is an image of my material properties. Any help would be greatly apperciated. Thank you!

      Can you try a constant Kxx and not temp. dependent - so just scope the defaullt Structural steel to all parts?

      Hi Erik

      Your advice seemed to stop the kxx error. Do you have idea how to include the temperature dependent material properties for shell elements? The part has gradient that go from room temp down to 15 K so in this case it would be necessary to include them.
