在做直流点分析时出现了如下错误，新手，求解答~

Automatic algorithm selection exhausted*** ERROR "ALG_SINGULAR_JACOBIAN" *** Singular Jacobian matrix.Some possible causes for a singular Jacobian matrix:- Model operating outside of its intended region of operation.- Node/subsystem with no connection to the reference (floating).- Current loops (voltage sources/inductors in parallel).- Missing equation and/or missing variable reference.Potential problem variables/equations:/xfrl3.xfrl3_1/i(l.l3)Partial results were written to the initial point "dcerr".execution time= 60.3 sec.messages given: 1 error

可能版本原因仿真文件打不开，估计是变压器的参数设置上出了问题，可以截个图上来看看。
