hello everyone!

i am doing something about induction heating in 3D. In the node Heat flux i gave the "General in ward heat flux" q0 a equation: 1.86*(293.15-T)^1.3
But the Simulation returned a error Information(see the attached picture)
can someone tell me, how can i fix it? i had used this equation in 2D, it could work very well

thank you very much!
