Description
This program is a version of BTEX20, the two region partial differential model. Two of the model parameters, PSg (exchange between plasma and isf) and Gisf (consumption in the isf) have been modified to be realDomains instead. This necessitates making Cp(t,x) into Cp(t,x,PSg,Gisf), Cisf(t,x) into Cisf(t,x,PSg,Gisf) and Cout(t) into Cout(t,PSg,Gisf). The details of making nested plots can be found at https://www.imagwiki.nibib.nih.gov/physiome/jsim/docs/UserNested The "Nesting" menu is on the second line of the nesting plot page, i.e. Message | Plotname | ...
