<div dir="ltr"><div><p class="">Hi,</p>
<p class="">I am trying to make the em_tropical_cyclone case in WRF V
3.4.1 run in nested configuration. I have finally managed to configure the
namelist option so as to make wrf.exe start, but when the run exists with a
segmentation fault every time. I am currently running WRF model with OpenMP, 4
cores and compiled with GCC, Gfortran. </p>

<p class="">Just for testing, I have tried em_b_wave in nested
configuration on my same OpenMP and it runs just fine.</p>
<p class="">I have attached both the namelist and the run log file
for nested em_tropical_cyclone case. I have already set ulimit etc so I don’t
think it is memory problem. I would really appreciate if you can help me with
this.</p>
