C compiler + discontinuities
lutz.d....@googlemail.com
I have got two problems.
1)
I switched to VS2017 recently. From this time on NSP did no compile anymore (i.e. Scicos + Modelica blocks). It seems there are problems with the paths to the c compiler. Before it worked fine.
Is there a possibility to:
- set the paths properly
- use LCC (works fine with Scicoslab)?
Thank you for a hint.
2)
With VS2015 the block diagram compiled but did not always simulate. The problems started as soon as there were discontinuities (in case you are interested I could send you the .cos and .mo files by email). Since I use Scicoslab (and hopefully NSP in the near future) for Power Electronics Simulation switching is more or less always present. Did the treatment of discontinuities or the (DAE-)solver change from Scicoslab to NSP?
Thank you again for any hint.
Have a nice evening.
Best regards,

I suppose that you use nsp version 1.3. I have investigated the pbs with VS2017 this week-end.
The way Microsoft deals with VS2017 is a bit different from previous versions, we cannot rely on
the registry to obtain the path of vcvarsall.bat
Thus the method I have implemented will work only if you have installed VS2017 in
the standard way.
You have to do the following: you take the msvc_configure.sci attached file
and put it in NSP/macros/system (NSP is the path where nsp is installed)
Then you go in NSP/macros/system and you delete
msvc_get_compiler.sci and msvc_configure.bin
you start nsp and type
add_lib('NSP/macros/system',compile=%t)
you should see a message like
Processing file: /usr/local/src/nsp2-trunk-gtk3/macros/system/msvc_configure.sci
then you, you restart and
If you type
msvc_get_compiler()
you should see the answer msc150
Note also that If you have multiple compilers on your machine you can use
msvc_select()
to choose the one you want to use with nsp/scicos
If you haven't installed you compiler in a standard path
you can edit msvc_configure.sci
search for msvc_check_product_2017 and change the code to fit your pathes
Then redo the add_lib call

For the second question, you can send me cos and mo files for tests
and yes, the version of scicos is slightly different between scicoslab and
nsp but I do not remember if the code has evolved for discontinuities treatment for
DAE.

thank you for your help! NSP now smoothly works with VS17. Thank you.
With the C compiler up and running I re-tested my simulations. Only half of them fail. So at the moment I must assume that the difficulties arise from my Modelica models and discontinuities are not a general problem.
So I want to apologize. I will investigate the fails in depth in the next time.
If something relates to the simulator I come back on you (and send you the files).
Best regards,
Lutz.
