Error compilation failed for load curve(FUNCTION ) in mat 106 sph

Hello i try to use mat 106 in sph simulation by Lsdyna. im use DEFINE_CURVE_FUNCTION for temperature dependent data like below

POLY(TEMP, 0, 5.31e+07,-3.521e+06, 7332,-3.333)

but get this error:

   part id 3 uses a thermal material type

   but no thermal option is active.

how to fix this problem?

best regards

    I suspect the function TEMP ...

    (a) is only meaningful when the analysis is a thermal-only or coupled thermal/mechanical analysis, and

    (b) requires a node number as an argument, e.g., TEMP(100) would be the temperature at node ID 100.

    thank you. how to write curve as a funection of temperature in every node? i want deffine temperature dependent material.
