Error: Circular variable dependency detected

Hello,

I'm trying to solve a 2D heat conduction model in a cylinder , wherein I'm using some equations (in variables module under definitions module) which are INTER-DEPENDENT on each other. But, on running, I'm facing the following error:

Circular variable dependency detected.
- Variable: mod1.c
- Geometry: 1
- Domain: 1

Those equations are not inbuilt in the modules, hence I've to write them separately. And the values of those variables has to be calculated iteratively.
So, kindly guide me why this error is coming and what can I do to rectify this. Is there a provision to write these equations anywhere else in the model.

Thanks in advance. :)
