【求助】Comsol 求解奇異矩陣問題
|
|
按照模型數(shù)據(jù)庫中的步驟做,但在求解過程中遇到“錯誤7111,奇異矩陣”的提示,細(xì)節(jié)描述為Exception: com.femlab.jni.FlNativeException: Singular matrix Messages: Singular matrix Stack trace: at linearization.cpp, row 2316, ( There are 1 void equations (empty rows in matrix) for the variable e0 There are 1 void equations (empty rows in matrix) for the variable e1 There are 1 void equations (empty rows in matrix) for the variable e2 and similarly for the degrees of freedom (empty columns in matrix) ) at com.femlab.solver.FlSolver.femStatic(Native Method) at com.femlab.solver.FemStatic.run(Unknown Source) at com.femlab.server.FlRunner.run(Unknown Source) at com.femlab.util.i.run(Unknown Source) at com.femlab.util.aa.run(Unknown Source) 請問,究竟錯在哪了,該怎樣改正?謝謝指教! |
