Hi Mr. Ivar

I'm trying to solve packed bed model builded from both mass and energy balances. I found error message : undefined value found (error 7248), it said there were 3111 equations give NaN/Inf for variables at the particle geometry. Here's the detail :


Exception:
com.femlab.jni.FlNativeException: Undefined value found Solvermodel
Messages:
Undefined value found Solvermodel

Segregated group X1


Stack trace:
at solvermodel.cpp, row 1808, (Undefined value found in the stiffness matrix.
There are 3111 equations giving NaN/Inf in the matrix rows for the variable CH4p
There are 3111 equations giving NaN/Inf in the matrix rows for the variable CO2p
There are 3111 equations giving NaN/Inf in the matrix rows for the variable COp
There are 3111 equations giving NaN/Inf in the matrix rows for the variable H2Op
