Fivespot test

Hi All,
I was reading reference papers on fivespot test, and one of them is by Wenqing Wang (2015). It is basically H2M type example; without external force, the mechanical response due to waterflood. For this example, I have also found the benchmark input files and attached them. However, the simulation stopped after 2nd step with messages as follows

outer coupling loop 2/2 complete

maximum coupling error (relative to tolerance) 2.24639e13

From the error message, it seems it is a coupling related issue associated with the *.num file. Any idea, what is wrong in the fivespot.num?

Regards,

Mohammad
