I am trying to run a viscoelastic analysis in Abaqus for a steel concrete composite beam. I am defining creep data of concrete by combined test data in viscoelastic property. I am confused about the value of 'js' and I provided value of 1/(1+phi) but Abaqus showed an error that normalized creep data must be greater than 1. Hence I provided it as (1+phi). Now it is again showing an error which states, "the matrix inversion routine ainv can onlybe used for matrices of order 30 or less". The data I provided for 'js' is 42 in number. same for 'jk'. I thought I need to reduce it but that also didn't help. Please suggest some solution.
