Hi,

I have been doing equation-based modeling to solve a user-defined PDE/ODE system of five equations (time depedent).

I need to satisfy an inequality constraint: w<=1, throughout the entire 3D domain. Here, w is one of the variables being solved for.

I have consulted a comsol blog in this regard: https://www.comsol.com/blogs/methods-for-enforcing-inequality-constraints/. However, couldn't find a way out.

Can anybody please help me to implement this domain/distributed inequality constraint in comsol?

Best Mehadi
