I am using the general form PDE option from the mathematics package to solve some equation and I would like to use adaptive meshing. The default error indicator is sqrt(comp1.u5x^2+comp1.u5y^2) (my dependent variables are u1-u5), however I have not been able to find any documentation on what this comp1 variable is. Does anyone know?

Thanks in advance.

Hi Sam,

"comp1" is your model basically. You can have several models in your study (usually you have one, but you can have more) and their are named according to the order you create them. So the first is comp1, the second is comp2 and so on.

Regarding you error, I am not sure I can help you because I have never used an adaptive mesh. But if your expression works for u1-u4 and fails for u5 it must be something related to this variable itself.

Hope this helps.

Best,

Nichal
