I am doing a 2 way coupled analysis between Fluent and Structural where temperature loads are transferred to Transient Structural and displacements are transferred to Fluent. I know that there is a Coupled Fields Structural-Thermal ACT that adds SOLID226 elements to a structural body, however it seems like the SOLID226 does not take body-temperature loads as inputs based on testing and the APDL Element Theory Guide.

SOLID186 elements seem to take body temperature as input.. but is this an acceptable element for this type of analysis? Or am I missing something about SOLID 226?

Thanks.

Ashish - thank you for the reference. I find that when I transfer temperature surface data - SOLID226 elements work fine. However when I want to transfer volumetric temperature data (body temp), SOLID226 elements are not able to capture this. This happens in 2-way coupling and also in 1-way coupling. Is there a setting I am missing with the 226 elements? I am clearly able to see temperature effects when using SOLD186 elements.
