idf file for a hydronic radiant wall heating system + thermal solar collector Hi Please, can I have a idf file example

thank you .

the dimension n means the number of variable (discrete and continuous) in the optimization ?

thank you, sir, for you feedback . in the Genopt manual (section 5.4.5 ) it s's mentioned that np=5*n up to n=15 . can you explain ,please , what mean the parameter n .

thanks

I'm trying to optimize a building design, by coupling EnergyPlus and an optimization tool GenOpt.

For that , I'm using a Hybrid Generalized Pattern Search Algorithm with Particle Swarm Optimization Algorithm (GPSPSOCCHJ) for discrete and continuous variable, but I can't understand how to determine the number of the particle for this optimization.

Please, give me an idea about the mean of this parameter(NumberOfParticle).

The command file is :

I need to run an example file (version 6). I was trying to convert the file to energy plus v7, but doesn't work.

Hi everybody

I need the installation password for EnergyPlus Version 6.0.

thanks

Hi all,

I am trying to figure out how can genopt 3.1 be coupled to energyplus 8.1 or just with energyplus 7.0.0?. what I need to change in genopt files that working with energyplus7 0.0?

Hi all,

I am trying to figure out how can genopt 3.1 be coupled to energyplus 8.2. I suppose cfg file should be modified, but i am not sure how and if should it be done.
