comsol计算找不到一致的初始值、传热T、奇异矩阵等问题如何解决?是怎么产生的?

找不到一致的初始值。
传热“T”
奇异矩阵。
有 361 个空方程(变量 comp1.T 矩阵中的空行)。
位于坐标: (-0.0017704,-5.51048e-19,0.02), (-0.00174082,0.000140791,0.02), (-0.00174082,-0.000140791,0.02), (-0.00170379,-1.06581e-18,0.02), (-0.00169884,-0.00028003,0.02), ...
与自由度类似(矩阵中有空列)。
最后一个时间步不收敛。
有哪位大神可以解答,万分谢谢!
