Non isothermal simulations using ECO2N module
I am trying to run some simulations using TOUGH2-MP and compare the results with TOUGH2.
The simulation runs successfully by TOUGH2 but when I tried to run it with TOUGh2-MP, I get convergence issues and simulation fails to run.
### no convergence in NSIN at * 1890 * for (T, XS, XLCO2) = (102.5102, 0.200000E+00, 0.100000E-05) P00=0.113029E+06
latest parameters are PS=-.778998E+08 X2S=0.170500E-01

But the same file works if I make it a isothermal case. Are there any issues related to non isothermal simulations using ECO2N module in TOUGH2-MP
Thank You George Pau
By changing MOP(16) to 6 the test problem and uniform grid worked for non isothermal cases, up to temperatures 100°C.
For non-uniform grid the simulations does not seem to converge even for temperatures less than 100°C and with MOP(16)=6.
I have attached Non-uniform grid, isothermal and non isothermal input files and
RCC3 test problem at temperature greater than 100°C and for non-isothermal simulations.
Could you please verify the attached non-isothermal cases.Reply
