Dear thank you for your quick reply. firstly I realized a mistake about hide/unhide usage that I can find the "hide level" button under the option of each variable (click mouse right button)., so it is fine. regarding the cloud size, it is always big in new gui when i sketch, but when i sw...

Hi I have same.experience with LAU The old.gui is more.user friendly. For example hide unhide can be done by individual vatiable in olg gui which we just right click mouse bitton and then can select hide level. W the old gui has partial.simulation whereas new.gui does not have Old gui can display a ...

Thanks Tom I also did not notice the mile per trip is constant, but still interesting how can this happen if there is a link between two variables. It should automatically make constant become AUX. Another thing I also just noticed is the number of NO UNIT is not consistent. For example, after I cha...

I just sent the error report, and had described the steps I took till the error happened
hope it can help enhance vensim

Hi again I found the ver 10 has problem with the "Check unit" which is supposed to report those variables with no specified unit or inconsistent unit. However, when I used the Check unit function to check my model (see attached), it prompted the variables even with the specified units, whe...

1) for the model I used to do the partial simulations which fails under ver. 10, see attached. I also copy the screenshot
2) Language English, I just cannot find the dictionary and where to place it

Thank you

Dear When I use v10, under new GUI, I cannot find the partial simulation anyway, I need to switch it to old GUI (under model header), but it does not work, there is always clash with error report, can you take a look? this work for previous under old GUI. I suggest to include this under new GUI for ...

Dear

I.saw.vensim has 9.3 version from prev. 9.2.4
May wr know what are the difference?

Thanks

Sorry for late feedback

Still the customs graph x,y division setting does not work under new GUI, pls advise.

Hi I just finished the replicate of the Urban dynamics model (URBAN2) in the book of the introduction to urban dynamics by Louis Edward Alfred etal. however, during the switch between the old and new GUI under version 9.2.4, I find my Middle house Level variable (named middle H) is missing ( in the ...

Dear I try to replicate the model from the article of "Dell’s SupportAssist customer adoption model". see attached model and the article. I currently face 3 problems 1) I have almost done except 2 variables which I have no idea how to formulate according to the equation based on the equati...

Sorry, I just find them by unhide

Tom just a simple basic technical question about the file of TranspoExcerpt The equation for the vairable of "Perceived Driving cost", there should be two variables: "Time to Perc the cost" and "Normal driving cost" Why I cannot see the two variables and the arrows in t...

Tom

thanks. I have done it in the model,
realized that linking the aux to set the initial value of stock, that vensim will only capture the initial value of the aux only. ( i tested it myself)
I just share the model to other members for their reference

Hi Tom Thanks your gudiance about lookup. Actually I know how to convert dynamo table functions into vensim lookup what i do not know is how to formulate the IMI (initial motivation index), the paper said IMI=MIO * MIP, which to me is the constant. but the MIO.K and MIP.K. For easy understanding how...

I am replicating the sales model from Prof John Morecroft's paper of Ratoinality & structure in behavioral model in business system. I translate the dynamo into vensim I am not sure how to set the constant of MIO and MIP (highlight in green) under the the inital value of IMI = MIO * MIP whereas ...

Thank you Tom!

I just read thru the Vensim help related to EXP and LN, LOG, really got it as you said

I will share it accordingly later.

Thanks Tom.

It is exactly what I need with the top one.

Dear I try to replicate the customer produces employment case study model in the book of Industrial dynamics by Jay Forrester. I think this is interesting and challenging job. I face question.how to convert attached 2 dynamo formula into vensim equation format. I.copy the two equations in attached. ...

Hi Tom Thanks a lot. I finally tried to use PULSE TRAIN functions to set 2 LEVEL as old value 1 and old value 2 of the cash to calculate the annual cash. If you can open my attached revised model, I get almost there. just the annual cash level lag 1 year behind. I do not why and how to fix it? Can y...

Dear I have a growing cash (LEVEL variable) for 60 months (5 years). I want to know how to create a AUX variable (e.g. to name it as annual cash) which can calculate the every year cash amount as the sum of the past 12 monthly cash. ( refer to attached file , see the value of the table of the cash l...

Precisely speaking

I can understang the file of " macro dynamics "that I cannot read the equation

But I totally cannot understand why I cannot read the equation of the file of Lotka cannot. Because I can really use PLP 7.2 to read the equation using sketch tool.

I guess I know what you mean. But I can really use PLP 7.2 to read and change equation for VPM (exactly the same model I attach Lotka). I cannot understand why pro 8.21 as a higher ver cannot do that for.me to read.the equation now. It become less capable using upgraded ver?? Can you check again the...

Dear I just purchased the PRO 8.2.1. (x64). Cool! But when I use it to open all my previous VPM file (see attached example Lotka), I can open it, but the vensim PRO 8.2.1 no longer shows the sketch tools and I am not able to see or edit the equation etc. But I could see and edit equation the same fi...

Tom

Thanks, it is very helpful to understand TREND functions much deeper with yout clear explanation at META SD.
