Dear Mr. Jeff,
First of all thank you for your reply I have checked the Type 952 as per
your suggestion. However for zero insulation thickness and with zero
thermal conductivity it is not working at all. For zero thickness means
there is no thermal conductivity of the insulating material. But when I put
default value of thermal conductivity with zero thickness it works.

Thanks & Regards,
