Hi,

Do you mean HelloWorld from DrModelica?
If so, it seems we made a mistake in the beta3 and used "simulation" command instead of "simulate" command.
Just change "simulation" to "simulate" and it should work.

We'll fix this as soon as possible with a beta4.

Cheers,

I tried Hello World from the delivered Open Modelica Notebook. I tried both simulation and simulate - both with the same result.

What OS are you running? And what is the output of checkSettings()?

I use Windows 7 SP1 X64bit version, i7 processor, 20MB memory. The case I am trying to solve is from OpenModelica Notebook with one change insted of simulation I use simulate
-----------------------------
I receive the following error message:
record SimulationResult
    resultFile = "",
    simulationOptions = "startTime = 0.0, stopTime = 4.0, numberOfIntervals = 500, tolerance = 0.000001, method = 'dassl', fileNamePrefix = 'HelloWorld', storeInTemp = false, noClean = false, options = '', outputFormat = 'mat', variableFilter = '.*', measureTime = false, cflags = '', simflags = ''",
    messages = "Simulation failed for model: HelloWorld

    timeFrontend = 0.0,
    timeBackend = 0.0,
    timeSimCode = 0.0,
    timeTemplates = 0.0,
    timeCompile = 0.0,
    timeSimulation = 0.0,
    timeTotal = 0.0
end SimulationResult;

Can anybody help?

Hi,

Do you have an older OMDev installed? If you don't know what that is then the answer is no.

If not, you can uninstall the beta3, install the latest nightly build:
https://build.openmodelica.org/omc/buil … ly-builds/
and restart and try again. We changed simulation to simulate in OMNotebook.

Cheers,

Dear Adrian,
I uninstalled beta 3 downloaded the latest nightly build and installed it:
I received the same error message as before:
record SimulationResult
    resultFile = "",
    messages = "Simulation failed for model: HelloWorld
Error: Error building simulator. Buildlog: gcc   -falign-functions -msse2 -mfpmath=sse   -I\"C:/OpenModelica1.9.0//include/omc\" -I.    -c -o HelloWorld.o HelloWorld.c
gcc   -falign-functions -msse2 -mfpmath=sse   -I\"C:/OpenModelica1.9.0//include/omc\" -I.    -c -o HelloWorld_records.o HelloWorld_records.c
mingw32-make: *** [HelloWorld_records.o] Error 1

"
end SimulationResult;
I wanted to mention that all example which are in OpenModel Notebook use simulation instead of simulate.
thank you for your help

Hi,

Ok. Something is definitely wrong with your installation.
In nightly build revision 15012 all DrModelica from OMNotebook has simulate instead of simulation.

Did you uninstalled 1.8.0?
In the HelloWorld example, instead of simulate or plot write: checkSettings()
and Shift+Enter. You should get something like this:

record OpenModelica.Scripting.CheckSettingsResult

    OPENMODELICAHOME = "C:/OpenModelica1.9.0-r15012/",

    OPENMODELICALIBRARY = "C:/OpenModelica1.9.0-r15012/lib/omlibrary",

    OMC_PATH = "C:/OpenModelica1.9.0-r15012//bin/omc.exe",

    OMDEV_PATH = "",

    OMC_FOUND = true,

    MODELICAUSERCFLAGS = "",

    WORKING_DIRECTORY = "C:/Users/adrpo/AppData/Local/Temp/OpenModelica",

    CREATE_FILE_WORKS = false,

    REMOVE_FILE_WORKS = false,

    OS = "Windows_NT",

    SYSTEM_INFO = "",

    RTLIBS = " -static-libgcc -luuid -lole32 -lws2_32 -lsundials_kinsol -lsundials_nvecserial -llapack-mingw",

    C_COMPILER = "gcc",

    C_COMPILER_RESPONDING = false,

    HAVE_CORBA = true,

    CONFIGURE_CMDLINE = "Manually created Makefiles for OMDev"

end OpenModelica.Scripting.CheckSettingsResult;

Let us know how your result from checkSettings looks like.

Another problem might be if your uninstall did not complete because omc.exe was still running (in the background).
To make sure everything is installed correctly:
1. reboot (so that no more omc or other OpenModelica programs are left running)
2. backup any models or notebooks you might have in c:\OpenModelica1.9.0\
3. uninstall the nightly-build
4. delete c:\OpenModelica1.9.0 folder
5. reinstall the nightly-build

Sorry about all this trouble.
We did not have these issues with anybody else and is rather complicated to find out what goes wrong.

Cheers,
Adrian Pop/

I did as you proposed. Interesting to see that on all my machines (4) with win 7 x64 I get the same results! If I uninstall Openmodelica V1.9 and reinstall Openmodelica 1.8.1 the problems run ok! Below the results from checkSettings:

record OpenModelica.Scripting.CheckSettingsResult
    OPENMODELICAHOME = "C:/OpenModelica1.9.0/",
    OPENMODELICALIBRARY = "C:/OpenModelica1.9.0/lib/omlibrary",
    OMC_PATH = "C:/OpenModelica1.9.0//bin/omc.exe",
    OMDEV_PATH = "",
    OMC_FOUND = true,
    MODELICAUSERCFLAGS = "",
    WORKING_DIRECTORY = "C:/Users/Chris/AppData/Local/Temp/OpenModelica",
    CREATE_FILE_WORKS = true,
    REMOVE_FILE_WORKS = true,
    OS = "Windows_NT",
    SYSTEM_INFO = "windows32 Ceres 2.6.1 7601 i686-pc Intel unknown MinGW
",
    RTLIBS = " -static-libgcc -luuid -lole32 -lws2_32 -lsundials_kinsol -lsundials_nvecserial -llapack-mingw",
    C_COMPILER = "gcc",
    C_COMPILER_RESPONDING = false,
    HAVE_CORBA = true,
    CONFIGURE_CMDLINE = "Manually created Makefiles for OMDev"
end OpenModelica.Scripting.CheckSettingsResult;

Hi,

I think i found the problem. I'll fix it and make a new nightly-build and let you know when is ready.
We will also make a beta4 soon to fix this issue.

Thanks for your input!

Cheers,
Adrian Pop/

Hi,

Try the latest nightly-build:
https://build.openmodelica.org/omc/buil … ly-builds/
make sure you uninstalled any previous OpenModelica installation.
Let me know how it goes.

Cheers,

What is the equivalent solvent for dasel  2  in open modelica 1.9  ?

It's just dassl.
The solver method "dassl2" was just a develompent version of the currect "dassl" solver method.

so long.
