fluid injection - negative stresse

Please login with a confirmed email address before reporting spam

Dear all,

I simulated an injection into a reservoir and get negative principal stresses. This means that the stress behaviour is compressive. I applied a "mass flux" (Darcy's law) in Poroelasticity module wirh positive value for inward flow.

Does someone know if the negative principal stresses are reasonable results?

Greetings Nastasja K.
