<div dir="ltr">Hello<div><br></div><div> I am trying to run the model for a nested configuration. However, my model stops running after few minutes!!! I found this to be present in all the three versions i. e. v3.3.1, v3.4.1 and v3.5. I think, I am doing something wrong. Please suggest something to overcome the issue.

I am not able to understand the exact problem. It looks like a run time issue. I feel I am not taking some namelist option in appropriate manner. However, I am not able to solve this. </div>
<div><br></div><div> Initially I tried with Milbrand MP but the model just stopped running after 1-2 mins. When I changed to Kesler MP, it ran for some time and then aborted. Again, after I changed the radt value from 20 to 30 mins it was running for some time more but again stopped on the way!</div>
<div><br></div><div><br></div><div>Please suggest something if possible.</div><div><br></div><div>Best regards</div><div>-- Jagabandhu<br></div><div dir="ltr"><div><br></div><div><br></div><div><br></div><div><br></div><div>
