[esp-r] Re: thermal bridges assessment

[Jon Hand]

The 3D conduction facility of ESP-r is rarely used - for most people knowledge of it has 
become obscure/lost.

ESP-r is able to deal with linear thermal bridges (so-called psi values) as an approximation
based on some steady state assumptions.  The zone geometry interface (prj) can detect different
join types for surfaces in a zone and allow you to associate a psi value per m of each of these
types of lengths.  Heat transfer via linear thermal bridges is reported in the zone energy balance.

Hi Olivier

I'm afraid you are not the only one with problems with this feature. Some time ago, I also tried to get this up and running, but was also unsuccessful. I managed to get past the core dumps at one point, but was not able to generate useful results. There is a Masters- or PhD thesis as far as I remember, you would need to search on the ESRU site, however. I wouldn't expect this to tell you how to make it work, though.

If you are prepared to code-crawl and find out what is wrong, I would be interested in the solution, anyway.

Best
Achim

Betreff: [esp-r] thermal bridges assessment

Hello,

I'm looking for elements about thermal bridges assessment. I did not find any information about multigridding and the dedicated exemplar (namely constr/adapt/cfg/g3d.cfg) does not run "out of the box", unfortunately. Actually it crashes with a segmentation fault. I do not know if it comes from an unpropper model or from my program installation.
1) Is there a tutorial / paper / note on the way of making proper use of the functionallity ?
2) Am I the only one having an issue with the exemplar ?

Sincerely,
Olivier
