Dear All,

 

I have attached the simplest of react files here I just want to have a

look at some saturation indices at very high ionic strength. I am using

the HMW database, but what I get as an answer is "ionic strength out of

range".

 

Any assistance appreciated.

Hi Grant,

 

Thermodynamics is not fond of zero species concentrations. If you set the HCO3- concentration to a small value, or remove it from the simulation altogether, I think you'll be back in business.

 

Hope this helps,

Craig
