<div dir="ltr">Dear all<div><br></div><div>can someone indicate the exact method of finding the correct time_step if the output data is required hourly and dx  = 48000 (parent),     9600 (nest) please? </div><div><br></div>
<div>I&#39;ve set it to 240 however I&#39;m still getting some constant data during the end of the last month of a 3 month long simulation. </div><div><br></div><div>Thanks in advance</div><div>Kind Regards</div><div>Sara Fenech</div>
