大神指教 这是关于管式反应器的数值积分，是中仿科技上的一个例题，但却出现了一个错误，导致建模无法进行，细节如下: Exception: com.femlab.jni.FlNativeException: Undefined value found Solvermodel Messages: Undefined value found Solvermodel Stack trace: at solvermodel.cpp, row 1808, (Undefined value found in the stiffness matrix. There are 2 equations giving NaN/Inf in the matrix rows for the variable u1 at coordinates: (0), (1), ... There are 2 equations giving NaN/Inf in the matrix rows for the variable u2 at coordinates: (0), (1), ... There are 2 equations giving NaN/Inf in the matrix rows for the variable u3 at coordinates: (0), (1), ... and similarly for the degrees of freedom, NaN/Inf in the matrix columns ) at com.femlab.solver.FlSolver.femTime(Native Method) at com.femlab.solver.FemTime.run(Unknown Source) at com.femlab.server.FlRunner.run(Unknown Source) at com.femlab.util.i.run(Unknown Source) at com.femlab.util.ae.run(Unknown Source) 如果能告诉我这个问题，定当重谢 |
