Hi Nori,
Just seeing your last comment.
I ran the simulations last night with your initial suggestion of settign
the $STORAGE to zero and I got some more reasonable results (picture
attached) .
The temperature decrease is still very small and it could very well be
due to the MFP file as you suggested. I will make some adjustments.
Thanks,
Ariel

Some more comments:
- $SPECIFIC_HEAT_CONDUCTIVITY in MFP should be corrected to
$HEAT_CONDUCTIVITY.
- Always output element velocity (see below) instead of node
velocity because the output of node velocity is wrong if your
problem includes fractures.
$NOD_VALUES
PRESSURE1
TEMPERATURE1
$ELE_VALUES
VELOCITY1_X
Best,
nori
