Please help me to understand more clearly about dimension in the Mathematics branch (in Comsol 4.2).
I would like to quote here some information from the User guide:
"The Mathematics interfaces are physics interfaces for equation-based modeling. They support several PDE formulation as well as general ways of adding ODEs, algebraic equations, and other global (space-independent) equations. You find the following mathematics interfaces in the Model Wizard’s Mathematics section:
• PDE Interfaces. These are interfaces for solving PDEs in different forms:
- Coefficient form for linear or almost linear PDEs, explained in detail in Coefficient Form PDE Interface (c).
- General form for nonlinear PDEs, explained in detail in General Form PDE Interface (g).
- Weak form using the weak formulation of the PDE for maximum flexibility. See Weak Form Modeling."
My question is that, the Coefficient form and the General form in the Comsol 4.2 is dimensional type or dimensionless type?
Thank you so much.
