大神指教 這是關(guān)于管式反應(yīng)器的數(shù)值積分,是中仿科技上的一個(gè)例題,但卻出現(xiàn)了一個(gè)錯(cuò)誤,導(dǎo)致建模無(wú)法進(jìn)行,細(xì)節(jié)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) 如果能告訴我這個(gè)問(wèn)題,定當(dāng)重謝 |
