Dear all

I am trying to solve thermal fluid structure interaction, but when i execute my solver it solves temperature for fluid then transfer the heat flux as boundary condition to the solid then solve the solid, but when it starts to solve the solid it give me floating point exception error, how can i know whats wrong:
DILUPBiCG: Solving for T, Initial residual = 1, Final residual = 5.6353e-20, No Iterations 2
DILUPBiCG: Solving for T, Initial residual = 0.107431, Final residual = 9.23625e-13, No Iterations 1
DILUPBiCG: Solving for T, Initial residual = 0.0970899, Final residual = 2.78566e-13, No Iterations 1
DILUPBiCG: Solving for T, Initial residual = 0.0837568, Final residual = 1.86213e-13, No Iterations 1
DILUPBiCG: Solving for T, Initial residual = 0.0962305, Final residual = 2.08175e-13, No Iterations 1
Setting Heat Flux on solid patch
Total HeatFlux on plate -5.45029e-14
Total HeatFlux on cylinder 1.78303e-13
DICPCG: Solving for T, Initial residual = 1, Final residual = 3.57181e-14, No Iterations 2
Floating point exception (core dumped)

can anyone helps ?
