Hello everyone, im trying to get an old model of ours back running. Whenever I use the old changes file (.cin), VenSim gives me an error at every point where "~~|" is in the file. If I remove it everything works fine, but I am worried that it might effect the outcome? What function did the...

perfect thank you, that solved the problem! Another general question, cuz I had a discussion earlier with someone: Is it possible that compiled and non-compiled simulation lead to (slightly) different results?

Equation of market tightness - regional: min(1,max(0, xidz( Reg Demand[Prdcr Region,Time setting]-imports for tightness calculation[Prdcr Region,Time setting], 1*Regional Available Capacity[Prdcr Region,Time setting], 2) )) so it is "( 1 , MAX (0 , XIDZ ( a , b , c )) )", just as you state...

sorry bout that. yea there is but I dont think its gonna help, since that is reallly specific to my model (the bold line is the one referred to in the error message): /* market tightness - regional */ for(forind0=0;forind0<14;forind0++) for(forind1=0;forind1<2;forind1++) { VGV->lastpos = 1181527+sub...

Here's the entire cmd output (sorry for the german in between): D:\Input Files>REM @ECHO OFF D:\Input Files>call "C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\bin\ vcvars32.bat" D:\Input Files>if exist mdl.obj del mdl.obj D:\Input Files>if exist "100219 v58_sim".dll del...

So, from one error to the next (I still get the "failed to compile the model (does not exist)" in the end). But this time I can actually show you the error log in the console: Now I get the "fatal error C1001: Internal compiler error" it specifically refers to this expressions in...

Alright, so it works! This time \comp and the other folders are actually in the right place (c:\users\public\vensim). I have no idea why they were under c:/program files/ vensim before (addtionially I assumed that was a valid place, since that directory is also mentioned in the "how to compile&...

Thank you for sticking with me anyway. I will do exactly that (reinstall both VenSim and VisualStudio with admin permissions) and then get back to you.

As I stated earlier, this is my compiled simulation path: "C:\Program Files (x86)\Vensim\COMP\" Here's the content of vensim.ini: [vensim] ModelsOld0= ModelsOld1= ModelsOld2= ModelsOld3= ModelsOld4= ModelsOld5= ModelsOld6= ModelsOld7= ModelsOld8= ModelsOld9= ModelsOld= print_options=1,1,0,...

No I'm running vensim.exe even though there also is a vensimdp.exe. Should I give that a try? How can the path not be set correctly if I edit and use the mdl.bat and then just copy the exact path in VenSim?

Yes I understand. I followed all you steps, but after I get asked if I want to compile and I click yes, I can see the DOS Window appear for a millisecond and then it disappears and the error from VenSim pops up ("failed tom compile the model (does not exist)"). So there is no chance for me...

The output I posted earlier was from running it myself. Here's what happens when I try to run it from vensim (simulate the model): Option 1: With a wrong path to mdl.bat I specifically get the error "couldnt find mdl.bat" Option 2: With the right path (in my case C:\Program Files (x86)\Ven...

Ok, I will try that. But why would that make a difference, if i can specifically tell VenSim where the mdl.bat is located anyway? So from my understanding it should not matter where the mdl.bat is as long as I put the right path in option->startup. Am I missing something?

Thank you for your answers. I think you've got the path to MDL.bat wrong. The instructions do say that the path to mdl.bat should be c:\Users\Public\Vensim\comp (or for older installations, “c:\program files\vensim\comp\”). Try that and see what happens. Vensim is trying to call “c:\program files (x...

What window are you refering to? Unfortunatly i cant share the model. Even if I try putting a "pause" at the beginning of the MDL.BAT I still get the same error.
The path to the comp folder is "C:\Program Files (x86)\Vensim\COMP\".

Yes the path to the comp folder is set in Vensim.

Yes exactly. I applied your suggested changes (comment out "ECHO OFF" and add a "pause" at the end) to the MDL.BAT. If I then try running the model in VenSim I get the same old error. So i thought I run MDL.BAT in a command prompt, so I can see what errors are occuring whithin th...

Thank you for your help. I adjusted the code according to your answers. If I try to run the MDL.BAT now, I get the following error (in the cmd console): "C:\Program Files (x86)\Vensim\COMP>call "C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\bin\vcvars32.bat" C:\Program Files ...

Yes, sure. Here you go: @ECHO OFF call "C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\bin\vcvars32.bat" if exist mdl.obj del mdl.obj if exist %3.dll del %3.dll if .%2 == . goto noinclude CL /O2 /c /I "%2" /DWIN32 mdl.c goto aftercomp :noinclude CL /O2 /c /DWIN32 mdl.c :a...

Thank you for your quick answer. I followed all steps but I still get the same error. Do you have any other ideas?

Best regards

Hello everyone, I am trying to get an 8 year old model running on a new computer and with a more recent VenSim Version. When I open my model and try to simulate it, I get the error "Failed to compile the model (does not exist)". I tried to fix that error by adjusting the paths in the mdl.b...

Thanks for your reply. I figured it out i had to merge my old vensim.c and some functions from the new one. Its quiet stressing to compile a new dll with the new header file because a lot of functions have changed in some ways. Thank you anyway.

Dear all, I'm trying to use an old model of ours and upon loading the external file I get the "External function mismatch 51050 (got 400) error" (http://www.ventanasystems.co.uk/forum/viewtopic.php?t=5512; http://www.ventanasystems.co.uk/forum/viewtopic.php?f=2&t=4462&p=15002&h...
