My name is chadnan I am working as a design engineer at KGC Projects, pune Indian
I have a query regarding Heat exchanger tube sheet calculation.
During the course of the calculation I had come across the Error which is as follows.
Warning: An Error occurred determining the Coefficent of Thermal Exp. Either
the Maximum temperature was exceeded or the reference index was 0.
Check the Coeff. ID in the Material Properties Dialog.

So please let me know the changes that has to be done in order to avoid the above error

First make sure that you have the latest service pack for your PV Elite. Check on our website for update.

Then, reselect the concerned materials from the database. this was an issue with some materials on 2011 original release.

If it still giving you the same error, go to the input for that material, press the button to see the material properties and you see input field for the Id for Coefficient of thermal expansion. Press F1 with cursor in that field to get a listing and find the closest match and type that value in that field. Some materials do not have direct match in ASME.

Thanks for the reply ,the problem has been sorted out.
Here i would like to tell the way in which we had sorted out the problem
1.We had selected an material from the database in which we had made changes to the thermal coefficient reference number(#) and we had saved the same with a new name for our reference.

2.We would like to let you know that most of the material do have thermal coefficient reference number(#) zero

Please do conform me whether the procedure followed by me as mentioned above in point1 is right or not.


thank you
With best regards
