Abaqus - Error in Porous Elastic materials (Soil-Rock-Mixture)

I'm new to geotechnical simulations on Abaqus, and I'm struggling to fix an error. The issue is with the sum of initial pressure and elastic tensile strength for a porous elastic material The error says it must be positive. Can someone help me understand which property I need to adjust to resolve this? Put simply, what should I do to fix this error? i trying from last 2 days.

Error ''The sum of initial pressure and elastic tensile strength for the porous elastic material in element 8001 instance part-1-Soil-rock-Mix- must be positive.''

Thanks in Advance
