I want to simulate the defect detection process on the Al block using the laser-ultrasound,and I don't know how to load the temperature field to an block as the body load.Hoping for help,thanks very much!

Hi

what do you mean to load the temperature as a "body load", do you want to fix the temperature ? ir is it the initial value of the temperature ?, If you have a thermal process fixing the body temperature is not really physical, but if you fix it on its borders + initial conditions, and no thermal process will take place then it will remain at that initial temperature

Good luck

I want to load the temperature field as body resource,like the pressure on the block,but i don't know how to realize this.Are there any models in the model liberary?

Hi

Define it in the initial conditions, that should do ;)
