cst warning.steady state energy criterion

my structure in CST is too big.(3m*1.6m*1.6* my dimension background material, frequency range is 0.05 to 0.15 GHz , and mesh operation is 15 per wave length per ) because I must to simulate this structure.
but it gives me this warning
"maximum simulation time reached. solver stopped. please note that steady state energy criterion has not been satisfied'
what should I do?

You should extend the maximum number of pulse.
Solve >> Transient Solver >> Specials >> Steady State (the default of maximum number of pulse is 20) please change this number larger than 20. 50 maybe is sufficient.

@freqzt
thank you for your regarding
