Dear Sir,

       I am new to ANSYS mechanical and encountering a problem that: WARNING, There is at least 1 small equation solver pivot term (e.g., at the UZ degree).

      This occurs during my simulation a steady-state therm in ANSYS mechanical, the thermal boundary comes from FLUENT simulation, then I have it mapped to a corresponding solid structure interface, however, there comes the above warning, so, what should I do to have this  problem resolved?

Does your analysis stop?

 THX Sir,

    The simulation does not stop, but its calculation speed is very slow, the phenomenon makes me wonder the accuracy of the simulation results.

     The warning comes out after I change the solid element type frome system default ones to solid 227 and solid 226.

     And, I use BONDED contact type between every two adjacent components.

     Also, are there any extra constraints in STEADY STATE THERMAL simuation?
