SOL600: error variable thermal properties in

[Alessio80]

Dear all,

I have to simulate a thermal contact problem with material properties depending on temperature. I use SOL600 of Nastran 2008 r3, and Patran 2008 r1 to build the model.
The problem is relative to material properties depending temperature in SOL600.

The .dat file seems to be successfully created, but an error occur in the solver. From the .out file the error is:



TABLE, TABLEM1 1
----------


table identifier 1

*** error this table id has already been defined
table name is tablem1
unit number 5
number of independent var. 1
read independent variable, function pairs
abscissa
temperature
number of data points 2
extrapolation is used if independent variable is outside range
first variable function
1 0.00000E+00 5.00000E+01
2 5.00000E+02 1.00000E+02

FIXED TEMPERATURE



This table is relative to the conductivity/temperature field. Anyhow I think that the project is correctly created since I just define a single table for the conductivity/temperature dependence and with constant material properties everything works fine.

Did anyone already struggle against this problem? Do you have any hint?

Attached you can find a simplify example file that demostrate my problem.


Thanks a lot
