Hi,

I have a simple model that simulates a concentrated flow causing crack propagation in the porous medium and I attached the screenshot below for better visualization. In reality the injection fluid is colder than the porous media, so I have to add thermal stresses as well. I thought about defining a constant temperature boundary condition in between the crack and give the porous media a higher temperature so they will exchange energy when running the model, but because the fracture surfaces get apart I think this may not be applicable. I will appreciate your advices on how to add the thermal stresses for this model.

Thank you
