thank you for your fast reply. I will attach a few pictures to further illustrate my problem:
1) The contacts are bonded for both glass/intumescent contacts and frictional for the glass/steel contact (since the glass probe is lying on the hotplate in this experiment) (friction coefficient 0.2)
2) a project overview with a temperature distribution at random timestep:
3) shows the last time step in the structural analysis with the intumescent fully expanded:
At the moment, as I said in my initial post, I always complete the thermal analysis first, then I use the temperatures calculated at each timestep in the structural analysis via “Imported Load” and perform the structural analysis. The way I try to compensate for the expansion in the thermal analysis is that I use a adapted λ (I divide the λ that the intumescent material would have at a certain temperature by the expansion rate).
So but what I want is as follows:
- Calculate time step 1 in the thermal system
- transfer the result to the structural system, calculate the time step there
- transfer the structural result back to the thermal system (if the intumescent has expanded, then the way the heat has to go through is longer, therefore the λ has no longer to be adapted)
- repeat until it is done
Can I do that somehow?
