Re: Arrow Options

Seems to only happen when changing arrows from default fonts to custom fonts. 1. Right-click on an arrow handle 2. Un-check the Polarity default button 3. Click on the font "button" on the right side of the "default button." 4. Change the font size, click OK The font does not cha...

Arrow Options

I noticed that when changing the defaults in Arrow Options, I have to make the change twice before it saves. For example, if I change the default size for the polarity, it does not save the first time. I have to make the change again then then it will save. Is this a known problem or am I doing some...

Re: Polarity Font size and color

I see it now! it's a little different. Had to unclick the default font button. Then click the font type and then the font option screen opens.

Thanks!

Polarity Font size and color

I am using PLE+ 10.0. In older versions, I was able to right-click on an arrow and change the size and color of the polarity sign. Can polarity font be changed in PLE+ 10.0?

Input Mode

How do you use Input Mode in PLE+? I am trying to create exponential decay for a stock variable. Can I use Exponential Input Mode with an output flow variable for this purpose? if so, how would that look?

Thanks,

I am using PLE+ and conducting experiments by evaluating combinations of variables at different values and running a simulation on each change. Is there a way to save the settings so I can recall the combination? For example, if I have 10 sliders and want to set them at high, med, and low values, an...

Incrementing Sensitivity Analysis Variables

Hello,
I am running a multivariate sensitivity analysis with 20+ variables using PLE+9.4.2. I am using a Uniform random distro. How do I set the increments for each variable (Example Min =1, Max = 10, Increments =.1)?

Thanks for your help!

Maybe I am wrong about the line graph. Maybe the line is not the average of the simulation runs at each point?

I am running PLP. How do we interpret the confidence band in the sensitivity graph? I assume the line graph represents the mean. the colored areas represent the area of the confidence boundaries. But in the 50% confidence boundary, the average line is outside the boundary. How can this be? Thanks in...

Re: Saved Results vs TimeStep Results

Think I got it! The duration of the pulse signal was longer than the time step which allowed the samples to occure beyond the saveper interval. Once I shorten the duration to <=time step, I get the tirgger occure at the correct interval and stays at 1 . Thanks for your help!! Appreciate it very much...

Making progress! I now have the IRE variable sampling on the SAVEPER intervals. Great! But it does not stay at the max value. The IRE variable is a tipping point. Once it reaches 1, it should stay at 1. The previous formula worked fine for this purpose but it was not sampling t the right interval. N...

Re: Saved Results vs TimeStep Results

Not sure I undertand. I am currently using the following formula:

IRE = SAMPLE IF TRUE(("IRE (∆I/∆Itp)")>=1,1,0)

I only want the ccalculation to occure every 500 units rather than ever time step ( which is .25).
