[esp-r] Re: 3D conduction model - exemplar

[Jon Hand]

A question about ground heat transfer....

The 3D ground conduction model has not been used very often in recent years
and with changes in compilers it might need some development work to be
useful.

And, you might want to get in touch with ESP-r users in Canada who have
a good knowledge of the BASESIMP (basement simulation) feature of ESP-r.

Subject: [esp-r]  3D conduction model - exemplar

Hi!

Have anyone checked out the 3D conduction model in the exemplar folder in ESP-r?

I am not able to do any simulation in the exemplar to see how the ground is affected. There is a warning at the beginning of the simulation saying "Error occured at record number 364 in the control volumes file"..

What I am wondering is, how can you do a 3D conduction modelling of the ground, when the zone called ground is a large box with the construction "fictive ground" at all surfaces? Fictive ground consist of the material "common earth" 100 mm. Is it not just a large box with air?

I want to create a 3D conduction model myself and simulate a heat storage facility under my model. But I am curious about how the heat transfer works in this "box".
