Re: [arts-users] cloudy simulations with ARTS

2019-12-03 Thread Oliver Lemke 
Hi Paolo,

For blas and lapack: Please make sure you have the libraries and development 
header files installed. I think the packages you have to install with yum on 
CentOS are called lapack-devel and libblas-devel. Having those hopefully fixes 
the compilation with GCC.

Since we use GCC and LLVM for development, the Intel Compiler is currently not 
tested for the development version. I recommend to stick with GCC for now.

Cheers,
Oliver

Re: [arts-users] cloudy simulations with ARTS

2019-12-03 Thread PAOLO VEGLIO 
Patrick,
yes, I got a few complains by arts about variables/methods not being defined if 
I try to use v2.2.64.

I was just looking at the development version today, but I have some issues 
compiling it (on Linux CentOS 7). I made sure that my machine meets all the 
requirements but I get a couple different errors, depending on whether I’m 
using gcc or the intel compiler.
Namely, if I use gcc, cmake can’t find lapack. This is the message I get when I 
run cmake:

CMake Error at cmake/modules/FindBLAS.cmake:699 (message):
  A required library with BLAS API not found.  Please specify library
  location.
Call Stack (most recent call first):
  cmake/modules/FindLAPACK.cmake:162 (find_package)
  CMakeLists.txt:248 (find_package)
I’d provide cmake with the path to my lapack but I’m not sure how to do it. 
Given what follows though, I’m not sure I would be able to compile the code 
anyway.
Cmake works if I use the intel compiler, but then the compilation fails with 
this error:

[  8%] Built target microhttpd
Scanning dependencies of target matpack
[  8%] Building CXX object src/CMakeFiles/matpack.dir/complex.cc.o
icpc: command line warning #10121: overriding '-std=c++11' with '-std=c++14'
/home/pveglio/arts/src/complex.cc(1529): error: more than 
one operator "*" matches these operands:
function "std::operator*(const std::complex &, const 
std::complex &)"
function "operator*(Complex, Complex)"
operand types are: const Complex * const Complex
for (; ai != ae; ++ai, ++bi) res += (*ai) * (*bi);
  ^

[...]

compilation aborted for /home/pveglio/arts/src/complex.cc 
(code 2)
make[2]: *** [src/CMakeFiles/matpack.dir/complex.cc.o] Error 2
make[1]: *** [src/CMakeFiles/matpack.dir/all] Error 2
make: *** [all] Error 2

there’s a whole lot in between but I can’t tell if it could be useful or it’s 
just the same error propagating throughout the code.

Let me know if you have any idea of what could cause these errors or you need 
more information.
Thanks,

Paolo

Sorry, but that is not the case. There are features used in those cfiles that 
are not at hand in v2.2.

In general, as you are interested in simulations around ICI, I would suggest 
that you switch to the development version. We have added quite a lot around 
scattering calculations since v2.2.

Re: [arts-users] cloudy simulations with ARTS

2019-11-28 Thread Simon Pfreundschuh 
Dear Paolo,


If you want to set the PND field explicitly you can find an example of how this 
is

done in the controlfile controlfiles/artscomponents/radar/TestIyActive.arts*. 
In particular,

there is a pnd field in the file controlfile 
controlfiles/artscomponents/radar/testdata/pnd_field.xml


Alternatively, you can let ARTS compute the PND field for you by defining 
scattering species with

corresponding PSDs. An example of how this is done can be found in the 
controlfiles

controlfiles/artscomponents/radar/scatsolvercomp/TestScatSolvers.arts*.


I hope this helps you to get started with the calculations otherwise don't 
hesitate

to ask.


Regards,


Simon


*This is the case in the development version of ARTS. I am not sure whether 
these were available

already in the latest release.

Subject: [arts-users] cloudy simulations with ARTS

Hello,
I’m currently trying to simulate measurements for the Ice Cloud Imager (ICI) 
that will be on board the EUMETSAT Polar System - Second Generation (EPS-SG) 
satellite using ARTS.
With the help of some of the controfiles in the classroom_exercises folder I 
was able to create clear sky ICI spectra. Now I’d be interested in adding 
clouds to my ICI simulations, but I’m struggling with the setup of the 
controlfiles. I downloaded the “StandardHabits” database but I couldn’t find 
any template to help me write the particle density number file that is required 
along with the scattering properties.
Would it be possible to have a sample pnd file and maybe also a controlfile to 
make sure I’m setting everything up correctly?
Thanks in advance for any help with this.
Best,

Paolo Veglio
