i like to manipulate the material property "heat conductivity" in depency of the maximum Temperatur in my transient 2D model.
Therefore i wrote the following expression into the "heat conductivity" section.
Code: Select all
Variable Temperature; Real MATC "if (tx>=(max(tx)-0.05)) 1e10 else 0.01"
But it does not work so far.
My question: can i use the expression "max(tx)" to determine the maximum temperature of the complete part?
Thank you very much

Background (but not important):
i want to mimick a squeeze out of glue between to plates by use of a thermal simulation (energy = glue volume, temperature = glue layer thickness).
For first attempt i like to use a 3-way geomtry like attached. There is a special behavior for this squeez out: the layer thickness decreases uniformaly because it is restricted by the two plates.
Therefore i have to manipulate the material property "thermal conductivity" in a special way: The thermal conductivity have to be "near infinity" for the "glue" and it has to be low for the "not covered" area.
Now the "operator "Maximum of Temperature" comes into play. I need to find out the max Temperatur in my Model in time step x and then adapt the material property "heat conducivity" for every time step.
