Ventana software support forum

Can you zip it and email it to me and I'll take a look?

There is little I can recommend unless I can see what you have.

" set print to 0"?

If you right click on the table tool, there is a setting for "print every". Set this to be zero.

You cannot get that information at the moment (unless you pass in a vector).

Forget about lastpos.

What are you trying to do?

I didn't want to bother the user with too many dialogs before loading his/her file, that's why I used the "!" as vdffile. I thought that Venapp could remember the name of the converted tab/vdf file to load it directly. Is it possible? No, it is not possible. I think you are going to have ...

I think it may be the SIMULATE>ADDDATA|! that is causing the problems. The "!" usually means the last runname, so will not work here as there is no runname.

Could you use GET DIRECT DATA instead? This will read the TAB file instead of importing it to a VDF.

You will need to upload the model if you want us to help.

Am I right in saying you want to select a variable, and then move to the sketch containing that variable?

If yes, then you cannot do this yet.

You are not draining anything from the level.

Try using

It's usually quicker to have a quick search in the help system as the info is there (and we do not always get to the forum immediately).

"in-renovation Old Buildings Rob" is going negative at t=2, this is having a knock on effect causing data overflow.

Hope this helps.

That licence is Pro, not DSS (so you cannot develop using the Vensim DLL or run command scripts).

Thanks Tony. I have little confusion about STEP function. If I want to use step function for different time slot such as 15, 45, 75, 90 etc. Shall I sue some like STEP(50,15)+STEP(50,45) +STEP(50,75)+STEP(50,90)? Or is there any other smarter option to do so? Try it and see if it gives you the resu...

Can you please fill in the serial number of your Vensim licence in your profile and I'll be happy to help.

Tony.

One thing to note. I've found a bug in the import process. Make sure that any info you have in the dat file actually exists in the model or Vensim gets into an infinite loop when importing the data.

This will be fixed in the next Vensim release.

Vensim does not import text files (and as you've found out, the file open dialog on the Mac will not let you change what files it can see).

You need to rename the file so that it is a .DAT one and not .TXT.

To completely drain a level, use "drain rate = level / time step".

Hope this helps.

Tony.

See the attached.

Make the multiplier a constant with a value of 1.

All I can suggest is using the loops tool and then copying the output to Excel and try and match those which include the parameters you are interested in.

Have a go at implementing it yourself, and if you have problems post the model and we'll take a look.

We are hoping to get the release out within the next three weeks.

It would have taken much longer to modify your model, so I've built a quick demo which uses ALLOCATE BY PRIORITY to do what's needed. The model has two sample sources. Then I allocate the capacity of the processing machine with priority based on the age of the samples in the queue (all samples must ...
