Reproducing the carbonate acidizing simulation

Hello everyone,

 

I’m a beginner at TOUGH REACT.

I want to reproduce the carbonate acidizing simulation of the paper . 

 

but, my simulation results is a slight decrease in porosity, which is not consistent with the results in the paper.

 

I have no idea what's wrong. I appreciate if someone help me.

Thanks a lot for your time and help!

  • I realized the problem is caused by high ion strength.

     

    I got the temporary solution by changing STIMAX.

    Thanks.
