error

Post by XIEWENBO »

I built a underground structure dynamic analysis model, but when I appear the following error analysis of the gravity...
warning SuperLU::solve(void)- Error 1 returned in factorization dgstrf()
warning NewtonRaphson:: solveCurrentStpe() -the LIinerSysOfEqn failed in solve()
StaticAnaysis::analyze() -the Algorithm failed at itertion :0 with domain at load factor 1
What is the cause of this problem

the solver typically fails at start because the model is incorrect .. either not enough boundary conditions or incorrectly defined elements, sections, materials.
