ANSYS APDL 进行不平衡激励启动过程的瞬态分析时,出现下列警告是哪里出问题了？
警告：① The MINREF field of the CNVTOL command has been assigned a default value of 1.0 for convergence on F. Check results carefully.
② BEAM189 will generate a gyroscopic damping matrix contribution(stationary frame ON on the CORIOLIS command) in a dynamic analysis.The element matrix will be non-symmetric.
③ The gyroscopic damping matrix (stationary frame ON in the CORIOLIS command) is based on small deflection theory. The large deflection effect (NLGEOM,ON) needs to be used with caution.
