Nonlinear solver did not converge.
Segregated group 2

Attempt to evaluate non-integral power of negative number.
Function: ^
Failed to evaluate variable.
Variable: mod1.ts.tle1.vpl1.ct ana, Defined as: ((mod1.ts.tle1.vpl1.A*exp(((-mod1.ts.tle1.vpl1.Q)/(mod1.T*R const))))*(sinh(((sqrt((((unit MPa cf*1.0000000000000001e-005)^2)+(3*mod1.ts.II2s)))*mod1.ts.tle1.vpl1.xi ana)/mod1.ts.tle1.vpl1.sa))^(1/mod1.ts.tle1.vpl1.m ana)))
Failed to evaluate variable.
Variable: mod1.ts.ect13, Defined as: (mod1.ts.tle1.vpl1.ct ana*mod1.ts.tle1.vpl1.nSdevXZ)
Failed to evaluate expression.
Expression: d((-(d(mod1.ts.ec11,TIME)-mod1.ts.ect11)*test(mod1.ts.ec11)-2*(d(mod1.ts.ec12,TIME)-mod1.ts.ect12)*test(mod1.ts.ec12)-2*(d(mod1.ts.ec13,TIME)-mod1.ts.ect13)*test(mod1.ts.ec13)-(d(mod1.ts.ec22,TIME)-mod1.ts.ect22)*test(mod1.ts.ec22)-2*(d(mod1.ts.ec23,TIME)-mod1.ts.ect23)*test(mod1.ts.ec23)-(d(mod1.ts.ec33,TIME)-mod1.ts.ect33)*test(mod1.ts.ec33))*(dvol),{test8})
Time : 0.7937500476837159
There was an error message from the linear solver.
The relative error (1.4e+002) is greater than the relative tolerance.
Failed to evaluate reaction forces at last time step.
Last time step is not converged.
