Greetings,<br><br>I've successfully completed simulations with
sf_urban_physics = 0 and 1, with the NLCD2001 3-class urban data and
would like to use the multi-layer urban parameterization
(sf_urban_physics = 2 or 3). I am unfortunately unable to use either of the options (2 or 3).<br><br>I'm using a 2-way nested grid configuration (3 total grids; finest grid delta-x, delta-y is 2km, with 40 levels in the vertical).<br>
<br>Initially (after successful real.exe completion), the model stopped
at a request to increase "nbui_max" to 5 levels. I changed the value
(initially 4) to 5, after which a request to increase num_urban layers
(i initially set this in the namelist to 1040) to 1300 was made. I did that as well, recompiled,
etc. ... now the model simply stops and it seems to stop in the noah
driver routine (perhaps while calling bep.<br>
<br>I've attached my namelist configuration and an example of the (rsl) output (with a high debug level).<br><br>Perhaps I am forgetting something that is required for execution of these multi-layer urban schemes. <br>
<br>Has anyone encountered similar issues?<br>
<br>thank you,<br><font color="#888888">Matei Georgescu</font>
