Hello everyone. I am trying to run a sensitivity analysis with Simlab and jEPlus using SOBOL method. The total number of jobs is 2800 and I imported all the jobs directly from a csv file to jEPlus.

The problem is that after all the simulation jobs are finished, when I think the program is writing the final excel file containing all the results (as I specified on my rvx file, the program stops responding and all the time I used to simulate is basically lost, since no output was written because the program crashed. I waited over 24hrs and there is no change.

Since this crash happened once before (utilizing jEPlus 1.7.2) I tried dividing the whole simulation into small batches of 800jobs. Anyway the crash happened again.

So, I have a few questions:

1. Since its my first time doing a SA, is it really normal to take over 5 days to do 2800 simulation jobs? The outputs I am requesting are Hourly Operative temperature and Hourly Zone Mean Air Temperature. My PC has 16GB of memory RAM and a i5 - 6600K @3.50GHz CPU.

2. Is there anyway to recover all the jobs without running the whole simulation again? According to my rvx file, after the simulation is done a csv file containing those two outputs should be created for each job and one containing all of them together should be created at the end, but since the program crashed, neither happened.

3. Looking at the picture below, there is around 4GB of ram allocated to jEPlus. Increasing this number would increase simulation speed? Is this crash happening due to this? Also, during the simulation "Maximum moemory available to VM:" is 4GB but "Memory allocated" and "Memory used by jEplus" is super low (92MB and 68MB). Is that common?

Thank you,

Vitor L.

Hello everyone! I wonder if there is any way to add simple equations and input to energy plus. The main reason that I want to do this is because I want to utilize an adaptive method (that is not ASHRAE55 and EN15251) as an input to my 'AirflowNetwork: Multizone:Zone' in the field 'Ventilation Control'. The easiest solution that I see is creating a schedule with varying setpoint temperatures according to outside temperature but for that I would've to input equations.

Is that possible?

Thank you
