Dear Reader, Good day. I have used COMSOL (Version 4.0a-4.3a) 7 years back. There are a lot of changes now in the GUI and the physics. I am no longer familiar with the new version and having problems running the model. I'm trying to model a fluid flow inside a box with one inlet and one outlet. A wall separates the box into two chambers. The inlet in positioned in one chamber and the outlet in the second chamber. But everytime i run the model, i keep entering this error.
"Undefined variable. - Variable: comp1.nitf1.rho - Geometry: geom1 - Domain: 3 Failed to evaluate variable. - Variable: comp1.spf.rho - Defined as: comp1.nitf1.rho Failed to evaluate variable. - Variable: comp1.spf.rhoinit - Defined as: comp1.spf.rho Failed to evaluate variable. - Variable: comp1.spf.kinit - Defined as: ((10comp1.spf.muinit)/(comp1.spf.rhoinitcomp1.spf.l_mix_lim))^2 Failed to evaluate expression. - Expression: comp1.spf.kinit"
Can you please help me point out where I'm missing in the model. Thank you in advance.
Here is the picture of the model and error. https://ibb.co/5j8ZNg2
