wrf compiling/installation

Good day from Tokyo. Our university supercomputer was recently upgraded, so it's also high time to compile the updated versions of WRF. Following the procedure for compiling WRF-Chem with the KPP seems to go smoothly (see attached compile.log). However, for more than a day of leaving it to...

Hello, I am trying to recompile WRFv4.5.2 on Derecho after making some small changes to module_bl_ysu.F. For some reason when both YSU and BEP-BEM are active, winds drop to nearly 0 in urban areas (see attached). At fault might be lines 1535-1538 of module_bl_ysu.F: ad(i,k) = ad(i,k) -...

Hello admins @islas @weiwang @kwerner @jordanschnell , @mgduda With the release of WRF v4.6.0, I have conducted a series of evaluations on the Weather Research and Forecasting Model Chemistry (WRF-Chem) version 4.6.0, utilizing the Intel LLVM Compilers and associated libraries. The purpose of...

Here are the details. When I try to compile the WRF-ChemV4.5, alwsys failed to find the four .exe in mian. Thins is my /.bashrc and I will post other files in attachment. As you can see in errors_comp.txt , there are some mistakes "‘ Makefile:50: warning: overriding recipe for target `.F.o'...

Excuse me, let me ask, recently I was installing WRF on my computer. I don't know all versions of WRF, I installed an error when compiling. Can anyone help answer where the error is and the solution? I had previously installed WRF and was successful in getting it to run. I don't know why it...

Hello, I’d like to understand if there is any measurable gain using vendor specific compiled WRF/WPS binaries vs GNU/GFORTRAN compiled libraries. Here is a literature that talks about Intel compiler. I’m looking to use AMD compiler - AMD Optimizing C/C++ and Fortran Compilers (AOCC) for WRF. For...

My WRF-Chem v3.9.1 used to compile successfully on Cheyenne. However, it is encountering compilation issues since the system was changed to Derecho. I have made changes to the WRF-Chem v3.9.1 code, so I cannot use a newer version of WRF. Here are the modules and directories loaded before...

I am a graduate student and I need to use the WRF model for my thesis entitled "Investigation of Wave Energy Potential on the Black Sea Coast". I will not use it for professional purposes, and I need to perform a simulation in the simplest way possible. I cannot provide more details since I am...

Hello, I was compiling WRF and an error occurred with ./compile -j 4 em_real. I will attach compile.log. What needs to be addressed? my env M1 Max MacStudio Homebrew

Hello, I am running WRFv4.4.2 and studying the registry to create only the variables I need in the output. There are numerous files in the ~/WRF/Registry directory, and from what I understand, the files used are different depending on the compilation options (em_real, or ideal, etc.), and there...

I am following the tutorial at Compiling WRF step-by-step. However, WRF still fails to install, with the error below: /usr/bin/ld: /wrf/Build_WRF/LIBRARIES/netcdf/lib/libnetcdff.a(nf_nc4.o): in function `nf_def_var_chunking_': nf_nc4.f90:(.text+0x5fee): undefined reference to...

I was trying to use a pre-compiled wrf but got this error multiple times as below: module_cpl.f90(7): error #7002: Error in opening the compiled module file. Check INCLUDE paths. [MODULE_CPL_OASIS3] USE module_cpl_oasis3 -------^ module_cpl.f90(3): error #7002: Error in opening the...

Dear Community, I am currently working on generating wind velocity simulations based on changes in radiation, specifically for simulating sea-breeze phenomena. Through a Google search, I discovered that the idealized case em_seabreeze2d_x in WRF can assist me in achieving this simulation...

Dear all, I'm using COAWST v3.7 (WRF v4.1) and want to compile WRF-chem and KPP, howerver I have problems in buiding executables. I've successfully ran WRF without chem. Here is the log file, Additionally, here are part of my enviroment settings in bashrc file: ### flex export...

I have an error during WRF compilation and it wouldn't create executable files. I try to follow this guide, Full WRF and WPS Installation Example (GNU) Everything is working until I try to install WRF. I couldn't found what's the error during the compilation Here's attached the log compile...

The recent releases of Ubuntu 22 and Ubuntu 23 by Canonical introduced several changes to their base operating system, including significant updates to the GNU Compiler Collection (GCC). Specifically, these versions have been upgraded to GCC 11 and GCC 12, respectively. A noteworthy aspect of...

So I am curoius about what OpenMP does and how does it help WRF run? I know you can use pnetcdf to read/write the output files which helps decrease runtime. I know you can use mpi to run more processes to help WRF run faster. How does OpenMP fit into all of this:?

So Intel has archived the classic compilers (ICC ifort icpc) behind a paywall. Now the new compilers (icx ifx icpx) are the free ones. I know there is a GitHub issue raised with this and a solution is pending release with WRF v4.6.0 Is there a timeline for the release? @kwerner or how to...

Hi all, I'm trying to compile WRF, but it's failing due to some errors. In the log.compile, there are always sentences of "undefined reference" around the error, so I think that is the cause, but I don't know how to deal with it. This is one of them: Could you please tell me what to do? I also...

Hello everyone, I'm trying to run WRF and now that I set up the model to run in a different time period, I'm getting the below error message (when I run ./real.exe): Missing surface temp, replaced with closest level, use_surface set to false. Missing surface RH, replaced with closest level...
