Nothing that I can think of.. Perhaps it is something more fundamental to the machine. I will rebuild it and see if the problem goes away
Many thanks for your help

Re: Problem with Vensim Loading
Many thanks Tom, I have renamed the ini files but still seem to have the same problem, which makes me suspect that something else has been corrupted. When I try to create a new model (or open vensim for the first time) the error message appears I am able to load existing models or for that matter ig...

Vensim model for Diabetes
My seven year old son has Type 1 diabetes and we are having a lot of challenges in regulating his blood/sugar levels. Given that we have heaps of measurement data, I was thinking that it might make sense to build an SD model to see if we can get a better understanding of what is going on. Wondering ...

deleting runs with multicontext dll
Hi I am running a large number of simulations via a webservice using the multicontext dll. When I run the simulations for a while the number of ctxtxx folders grow and since my runs have a lot data, they each take up a lot of space. Is there a way of deleting the run data after I have had the opport...

Loops in external functions
Given that it is necessary to specify the number of loops in an external function. Is there a limit to the number of loops that an external function can have?

Re: Using External Functions with the Multicontext DLL
Many thanks, You're right, the problem was with the version of Vensim.h file I was using. When I went back to an earlier version (which had the correct External Function version number) it worked I suspect that the vendlstc.dll file that I am using is from an 5.10d or possibly earlier. Would that ca...

Using External Functions with the Multicontext DLL
I am trying implement several external functions while using the multicontext dll (vendlstc.dll). Currently the external function is not working and I suspect it is because I haven't linked my external function to the appropriate .lib file. In the script for the external function I see the following...

Re: What improvements would you like to see in Vensim?
It would be helpful for me if external function integration was simplified - particularly for cases where loops (such as 'do while') are needed
