Gas exsolution

Hello guys,

Is there any existing plug in to simulate gas exsolution in confined aquifer satured in methane?
Thanks

Or any suggestion of expression based on pressure.
Storativity can be modified by gas exsolution linked to pressure ([i]effect of natural gas exsolution on specific storage in confined aquifer underdoing water level decline, Richard M. Yager & Johm C. Fountain, Groundwater - July August 2001[/i])
Is it possible to modify materials properties such specific storativity during a simulation like a time series dependance but not pre calculated by the hydrogeologist?
Thank you for your advices

It does not make sense to link a timeseries to a material property, if you want to modify the timeseries while simulating. The link between timeseries and a material property is set once and feflow writes the whole data into the model files (this works only for BCs etc.). A modification of the timeseries afterwards does not effect the material property.

you could write a plugin, using the functions:
IfmGetResultsFlowPressureValueAtXYZ
calculation of Gas exsolution
IfmSetMatFlowStorativity
