2017-03-21 05:09:51 -0500 asked a question Compiling the Fortran Source Code of EnergyPlus

Hi,

Can anyone please share the process to compile the Fortran source code of EnergyPlus. All the methods available on the net are for compiling C++ code but none for compiling the old EP's Fortran code.

Thanks in advance.

2017-02-01 08:29:24 -0500 asked a question Adding a new EMS:Actuator

Hi,

Is there a way to create EMS actuator for total transmitted irradiance for a surface. There is an Output variable for this, which mean EP calculates this which is given to final heat balance equation. I want to give a new transmitted irradiance which will be calculated by Simulink and I will give it to EP via BCVTB.

Thanks

Hi, Thanks for your answer. I think I can dig into it work from there.

Hi,

Yes, I am aware of these tools, but I guess these are just meant for optimization or parametric simulations. I am able to make a Py script to make multiple idf files but am stuck after the simulation runs.

I wanted to know of a way to post process the data files from 1000s of simulation runs. If anybody can share Py script for post processing multiple CSV files, to calculate sensitivity of one parameter or even combo of multiple parameters towards certain output.

Would it be possible for anybody to share how exactly is sensitivity analysis done in Energy Plus? What are the exact steps that have to be taken?

Is there any Excel plugin for this or do we have to link up EP with Matlab using BCVTB or using a Python code for analysis of final result files?

2016-06-22 09:25:56 -0500 asked a question Heat Flux at the surface nodes, CTF vs CFD method

Hi All,

First of all, can we consider "Face Conduction Heat Transfer Rate per Area" on a surface face(inside/outside) in ConductionTransferFunction method same as "Surface Heat Flux" on the boundary nodes of a surface in ConductionFiniteDifference method. Same not in the terms of value but in the terms of meaning and how these both values are calculated in EP.

I am comparing heat flux from an experimental data (DSC) of a specimen with a virtual specimen in EP and in that error results from CTF algorithm looks better than CFD algorithm.

Has anybody experienced this before and if so what can be the reasons?

Edit- For more details-

I am simulating a conventional wall, subject to sinusoidal temperature excitation on the outer layer and constant temperature on the inner layer, with both CTF and CFD methods.

I have experimental data for comparison, and results from CTF simulation are much more consistent with experimental data then those with CFD. In particular, the heat flux at the indoor surface with CTF is (as expected) perfectly sinusoidal, while with CFD method it shows quite a large deviation from a perfect sinusoidal.

Thanks
