MPC 184 (Rigid/Link) elements are be capable of simulating rigid connection with thermal expansion.

    The process requires defining a Remote point with behavior set to "Beam". The attached extension (tested with Ansys WB 2022R2) converts the Beam elements to MPC184 behind the scenes and assigns the user defined coefficient of Thermal Expansion.

    The temperature property defines Structural temperature for the MPC elements starting from a particular time-step. This can be controlled with the "Activate" column.
