I am using the IMASS model for brittle rock modeling. I want to set my tensile strength cutoff to 10 MPa. The software documentation says that you can set the tensile strength with

An error saying that calc_stren_tension is a read-only property appears. This makes sense as the manual later states it. Is there a way to set the tensile cutoff with a single value? Is inputting tension as a strain-dependent table the only option?

Hello @lfgomezdea,
The IMASS property calc_stren_tension is a calculated property defined as

where s is the Hoek-Brown parameter (defined in eq 3 in the IMASS doc), sig_ci is the uniaxial compressive strength of intact rock and m_b is the intial Hoek-Brown parameter (see eq 2).

Yes, with the properties I am using I get a tension of 90 MPa and I want to modify it to 10 MPa without using the in_weak_tabletension property. Is this possible?
