- Metric: The metric used to bench is the **total time of the simulation in seconds excluding initialization and I/Os**. (For more details see the validate.sh script).
A copy of the validation metrics are written in a **file metric-$TEST_NAME.log** copy in turn in the folder **$TEST_NAME/results-$SOFT_NAME-$TEST_NAME**
- physical: The value used for **physical validation** is the **dt value** at the end of the simulation log file.
dt: calculated value that incorporates the temperature, density and gas velocity
of all the cells in the simulation. This value also depends on the size of the cells
(i.e. the size of the mesh) and therefore depending on the granularity of the mesh
the dt value will be greater or smaller. For example in the small case (A.K.A DEBUG)
dt will be of the order of 10^-1 to 10^-2 because the mesh used are relatively large
while for the other two cases this value will fluctuate a few tens of percent around
10^-5. In fact, in ramses the errors get bigger and the value beyond 10^-7 or 10^-3
the calculations are clearly wrong. Finally, depending on the machine used, the
value dt will not be exactly the same because to calculate dt, the values pass
through an MPI_Allreduce depending on the MPI library used.
