HI,<\/p>\n

How to define thermal conductivity K(T(t)), which is a function of temperature 'T' at current simulation time 't' in APDL? Also, how to set the thermal conductivity of killed elements to negligible value?<\/p>\n

I know, one way of doing it is by manually filling the table with temperature value and corresponding thermal conductivity. Is there a way of doing it automatically, where based on the current temperature value the thermal conductivity changes?<\/p>\n

 I am trying to solve coupled problem (sturctural+thermal) in APDL. When plotting temp vs time plot in time-history postprocessor, the node shows a rise in temperature at the time when it is in killed state. I tried to further reduce the thermal conductivity value to 1e-30 by using 'ESTIF' command, but it's not working.<\/p>\n","protected":false},"template":"","class_list":["post-163130","topic","type-topic","status-closed","hentry","topic-tag-coupled-simulation","topic-tag-ekill-elements","topic-tag-mechanical-apdl"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
