Hello i try to use mat 106 in sph simulation by Lsdyna. im use DEFINE_CURVE_FUNCTION for temperature dependent data like belownPOLY(TEMP, 0, 5.31e+07,-3.521e+06, 7332,-3.333)n but get this error:nBeginning of keyword reader n *** Error compilation failed for load curve 3n *** Error 10907 (KEY+907)n Incorrect type of argument for functionn *** Error compilation failed for load curve 4n *** Error 10907 (KEY+907)n Incorrect type of argument for functionn *** Error compilation failed for load curve 5n *** Error 10907 (KEY+907)n Incorrect type of argument for functionn *** Error compilation failed for load curve 6n *** Error 10907 (KEY+907)n Incorrect type of argument for functionn *** Error compilation failed for load curve 7n *** Error 10907 (KEY+907)n Incorrect type of argument for functionn *** Error compilation failed for load curve 8n *** Error 10907 (KEY+907)n Incorrect type of argument for functionn Memory required to process keyword : 1725526 n *** Error 20122 (STR+122)n part id 3 uses a thermal material typen but no thermal option is active.nhow to fix this problem?nbest regardsn

I suspect the function TEMP ...n(a) is only meaningful when the analysis is a thermal-only or coupled thermal/mechanical analysis, and n(b) requires a node number as an argument, e.g., TEMP(100) would be the temperature at node ID 100.n

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