SteelMPFuniaxial material is showing error while running

[kaustavsengupta]

Dear Users,

I am trying to calibrate flexure critical columns (with fiber section). I am modelling concrete and steel (reinforcement) with Concrete02 and SteelMPF respectively. When I am using SteelMPF uniaxial material for modelling reinforcement material, it showing the following error - "couldnot create uniaxial material"

Please suggest a solution to use the material or suggest an alternative for the material.

Thanks and regards,
