I have a known temperature field in the air domain (the red,I know the temperature change over time for each node), there is a shell structure(the blue) in the air domain, and I want to get the temperature change over time for the structure.
I tried using *BOUNDARY_TEMPERATURE_NODE to load the temperature of the air, *CONSTRAINED_LAGRANGE_IN_SOLID for fluid-solid coupling, and selecting thermosolid coupling in *CONTROL_SOLUTION, but the end result is only the temperature field of the air domain, temperature distribution of the structure does not correspond to the actual situation.(The picture below shows how I want it to look)
Is there any error in my thinking? Which keywords should I use to achieve the results I want.
Is the red air domain a solid? I'm not sure if it would work but you might be able to use *Contact_surface_to_surface_thermal and use segment sets between the red and blue. I'm not sure if that would work since the meshes will be initially penetrating.
Also, have you tried changed *Control_Solution SOLN to be thermal only? I only say this because it doesn't seem like you are interested in any kind of structural analysis, only the thermal.
Also, here's a deep dive on this topic within Dyna that might be of use:
