      What doe the error messages mean in ansys solution information.?

      I am able to solve the problem setup using Structural steel material for both geometries. But when I applied different materials Sic_Pores and Sic_Sic for each geometry I got the fallowing error.

      It looks that the element is inverting due to the thermal strain. Can you check the CTE values and temperature change due to thermal condition, if it can cause element inversion?
      See if turning on the large deflections helps.

      In the Solution setting, try Large Deflection = ON
      You could also try setting Auto Time Stepping to "On, then
      initial 25
      minimum 10
      maximum 1000
