Result Structure
The result returned by the call to the simulation command is a structure with many fields:
Example 1:
set res = simulation(tb())
set err_code = res.simu_status
if (err_code == 0)
fprint(stdout, "Simulation succeeded.\n")
else
fprint(stdout, "Simulation failed!\n")
endif
Example 2:
Table 18-2. ECL Result Structure Fields
Field
Description
avg_newton Average number of Newton iterations
newton_iter Number of Newton iterations
tot_elements Total number of elements
simu_status Return code of the simulation (0 is OK)
simu_time Simulation elapsed time, in seconds
nb_steps Number of accepted time steps
nb_rej_steps Number of rejected time steps
nb_lte_rej_steps Number of rejected time steps due to LTE
nb_nodes Number of nodes
nb_proc_used Number of processors used
set res = simulation(tb())
set elapsed = res.simu_time
fprint(stdout, "Elapsed time: %.1f s.\n", elapsed)
See “Variables” on page 821, “Flow Control Statements” on page 835, and the fprint function
for more information on the concepts used in these examples.
