Hey COMSOL-Experts,

I want to limit the dependent variable s for an intervall ( 0<s<1). How do I do this in COMSOL 4.1?

Thanks for help.

Best regards
David

Hi

For posprocessing or solving

for solving I would say via some clever BC set-up depending on the type of variable,s, physics etc

for postprocessing, either using the filter or a "data-set" operation

Good luck

Hi Ivar,

Could you please give me more details about the clever BC set-up dependent on the type of variable, s, for solving? In my model coupled diluted species transport moduel and a user-defined general PDE, where the dependent variables are "cm" and "um", I want to set the limit 0<um<0.7. The two physics fields are caculated in different domains seperately but coupled via a mass flux at the liquid-gas interface. What can I do?

Thanks in advance.
