Ventana software support forum

Hi, I optimized my model parameters. I copied file with data folder. Now when I run the model I get this message "ERROR: Unable to open the file BASERUN.vdf. " why is this error message coming while I can see the model out put in graphs. Is the output incorrect if this message comes? Or th...

Is there any help available for building a Venapp- a management flight simulator. I have a model which I need to present to client. Aim is to play and experiment with the model without getting to know the equations. Unfortunately, publishing with Forio Systems is not possible as client has quite a l...

Thanks for your feedback and suggestions.

Model behave a bit better now. I have made aging of BP equal to zero.

I replicated the structure for BP. For age 25 to 35 the BP attribute vale remain constant but for age 36 till 65 with each step of simulation the BP value changes. My requirement is to keep these values constant for each age cohort for entire simulation run. As there is no inflow or outflow exept ag...

Thanks once again.

I will implement BP as a co-flow structure. I see that you have corrected equations too.

You added recruitment inflow to model, I can understand the logic, but in my case the population doesn't change, it only ages. So, I made it equal to zero.

yes, SBP is blood pressure. And it is an attribute of a patient. Each age cohort has different SBP. To me Array was the only option I could apply. Nevertheless,
I will be waiting for your guidelines.
Thank you

The EXCEL file is the one I want to input as in BASELINE POPULATION in the model.
there are no births or deaths, population is fixed.

My aim is to have for each age cohort with number of patients (male and female) and their respective SBP in the BASELINE POPULATION.

Hi Tom, Thanks once again for your reply. I feel quite embarrassed that despite your so much input I am not able to get what I require. I tried GET XLS SUBSCRIPT its works. Then I put that subscript in equation for stock and aging. But as before, problem is from giving initial value for population s...

I tried GET XLS data. But I am not been able to get what I want; for each age cohort, number of patients and their blood pressure.

I would really appreciate of there is some some vensim code for this.

Thanks Tom for your reply. It was quite helpful. I tried with GET DIRECT CONSTANTS. It dint't work :cry: I added a subscript of SBP, but when I ran the model it gave me dimensional inconsistency. For each age and gender it is mapping for each element of SBP group. AGE24 MALE SBPAGE24 AGE24 MALE SBPA...

Ok I figured it out.

For example, set Age subscript for BMI. In equation editor add vale vertically followed by a , and last value no comma and hot enter.
Watch out for array dimension. You must enter same number of values for BMI as Age, other wise error will generated.

Hi, I am building a population level model with aging and population having attributes. The data I have looks like this Age # of Patients SBP (average) HbA1c (average) BMI (average) TotaltoHDL (average)[/b] 25 1 109.8082 10.2271 31.6328 4.2518 26 1 97.0217 7.2728 30.2394 4.1116 27 1 131.4675 6.3382 ...

i am trying to learn the logic behind age.mdl file available in the Sample/Extra in Vensim help.
can anyone show me how the aging variable is split?
