[XTPLOT crashing after apparent successful X1T run]

Thanks Jia.  I think this is a case where the student merely plugged something into a previous X1T run.  I thought it might be the dxplot parameter, but I wasn't sure what it should be set too.  Is there ever a reason to have a dxplot of 1e-4?  Is there a dxplot value that would be too high?

Thanks.

[XTPLOT crashing after apparent successful X1T run]

Hi,

Two of my students and I ran into an issue where the XTPLOT never rendered after an apparent successful run of X1T.  The same parameters were used in a successful REACT run, so it is unclear what happened.  

Regards,

Rob

[Using X1T to model O2 transport; why does porosity matter when flow is in cm/day?]

Hi Jia or Brian,

My class has been running X1T to model the transport of O2 created by the reaction of CaO2 (oxygen release compound).  I have created a PPT file to illustrate our observations.  There are two questions.  1)  How does the O2 concentration reach much greater than background concentrations at > double the distance  than the flow would allow ?  2) Why does the porosity alter the distance the O2 is transported when the discharge is given in cm/day?  Why should porosity matter when these are the discharge units?

Regards,

Rob
