After simulating several cases with the use of a joblist I get results but the output file also mentions a fatal error. Are the results reliable if there are also fatal errors?

Thank you in advance.

kind regards,

I am getting a problem while using the "Run ReadVars" under the "Utilities".
When I use it without any "Export" option then it works fine i.e. eplusout.csv is generated with filtered results in all job folders.

But when I want to generate a summary table too i.e. check the option "Export all results to one table, with name" and press "collect results" then problem comes. It generates eplusout.csv file to first few job folders (say 5 or 7 out of 24 jobs) and then nothing happens after that. No more eplusout.csv file is generated in other job folders nor the combined table ("processed_results.csv"). And I do not get any error message.

Please suggest possible solutions.

Thanks in advance,

regards,
Prashant

Hi,
I'm trying to run a simulation with the ID job list generated from SimLab LHS (joblist.csv): 5 parameters and a total of 500 jobs (a total of 2500 values) in an annual simulation looking for temperature output.
I assume that because of memory issues, the simulation does not run. However, when I run only 10 jobs it does the simulation.
What can I do to get the simulation with a bigger sample than 10 from SimLab in order to execute later the SA?

Many thanks.

Hello,
I am trying to find the optimal first cost for a net zero energy building. I programmed the constraints and objective as shown below. When I run jEplus+EA, it keeps switching the best solution so that sometimes it is above the constraint limits for energy to be above zero, thus not a net zero energy building. I have a feeling this has to do with the weighting, but I am not sure. See attached picture for an example of the scatter plot. Any ideas on why the optimal solution isn't falling withing the constraints?

Hello,
I am experiencing some problems with jEplus and TRNSYS. In fact, whenever I run a set of simulations using the detailed radiation mode, the simulation does not even start as TRNSYS cannot find the .VFM (view factor matrix) file. Running the simulation directly from the Simulation Studio works just fine. Has anybody found this problem and perhaps has a walkaround?

Thank you for your time.

Hello colleagues,
       I'm using jEPlus+EA_v1.7.6_beta and still a rookie. And I'm learning something about Day-lighting and its relation with electric lights, I want set the  Day-lighting factors and electric lights power consumption as Constraints, Then I got problems, I didn't know how to extract the value of  Day-lighting factors....
       By the way ,Is there kind of forum about EnergyPlus? in need too.
       thank you

Hello.
I'm using jEPlus version 1.5.2 to run my simulations because the latest version (which says 1.6.4 in the GUI) does not extract any results to csv files. I saw an earlier forum post referring to a bug fix present in 1.5.2 to deal with this problem, so I went with that version.
When I run a random sample of approximately 10% of my jobs everything works fine and I get all of the requested results extracted to a csv file. However, when I try to run all 81 jobs in my simulation queue it crashes at the end as it is trying to collect results. I get this message:

I have made sure that 64-bit Java is installed, but as I'm not a super computer-savvy person I don't know what else to try. Please help!
Thanks,

Dear all,

I am new to this forum and I haven't used JePlus before (I am familiar with EnergyPlus). I hope some of you can help me with the following problem:
I have a file with 1 million different buildings and for each building I have ~30 different building characteristics (area of the building, insulation rate, ventilation system, heating system, type of dwelling etc.).
I would like to simulate those buildings.
I know 30 building characteristics are not enough to make a proper simulation therefore my plan is to make a basic model and change characteristics I know. Because it is impossible to change these 30 characteristics manually per dwelling I am hoping that jeplus can help me with that. Do you think this is possible or should I use another tool to do this. And if you think JePlus is a suitable tool can you give me some advice how to start?

Thanks in advance for your help!

I tried looking at the documentation but could not find this information. What is the color scheme represents after the optimization runs?
I have multiple points with red or blue in a batch of gray points. I get that the highlighted once are the solution within the constraints, but the colored red and blue are not clear.

The screenshot is attached.

I am trying to set a optimization problem  from JEplus. However, following what is suggested I wanted to use the alloutput.rvi from example file. However on my local simulation I could extract data from eplustble.html but non of the rvi that uses 'eplusout.eso' and 'eplusout.csv' have any results collected. Further, under the simulation folders I don't see any 'eplusput.csv' at all but eplusout.eso is present.
1. In the absence of eplusout.csv I extracted all my required values from eplustbl.csv. Does it make any difference?
If the above is also acceptable
2. My objective is to reduce the total annual cost and minimize peak electricity kWh and have minimum number of unmet hours from the simulation (while having minimum warnings).
Does this mean I have to have 3 objective?
I have the following from the reults file
Obj1--number of unmet hours hrs---C1
Obj2-- Annual cost       $           ---C17
Obj3-- Peak energy kWh            ---C18

Do I need a constraint defined? what is scaling used for?
3. How to define objectives
As this is a minima or maxima problem, how can I pick the lower and upper bounds? Is this a simple guess between 0 and some value higher than I get from single simulation?

AllCombinedResults.csv file is attached.
