Dear users and specialists! Please help me to understand what the error code says. it's not about 1 code. Generaly I want to understand how decoding error codes. For example, dirung a simulation in Plasms (Plasma Conductivity Coupling + Magnetic Fields + Laminar Flow), i get an errors: Failed to find consistent initial values. Division by zero. Function: / Failed to evaluate variable. Variable: mod1.plas.Te, Defined as: (2mod1.plas.en)/(3mod1.plas.ne)

My main question is about (for exapmle: mod1.plas.Te - mod1.plas.en etc.) What it menas? How can I find the path to this error place by knowing the error code? Are there any instructions on this?

Thanks and Regards

Hi Luigi,

In this case, it seems like mod1.plas.ne in the denominator of the expression is zero, since you get the "Division by zero" message.

To find its definion, do a search using Ctrl-F, as discussed in these threads:

Did you have "Equation View" turned on in the Show button ("eye" icon at the top of the Model Builder) when you ran that search?
