[esp-r] Re: thermal lag

[Geissler Achim]

Hi Pat,

 

depending on what depth of information you are looking for, ESP-r has that info for any multi-layer construction readily available. You just need to change the "results flag" from 2 or 4 or whatever to 3. Then you get 3 temperatures for each layer at every timestep (surface, center, other surface).

 

Now if e.g. a concrete wall / slab is of detailed interest, you can split that up into more layers - ergo more temperatures. For higher time resolution, of course, you can use smaller time steps.

 

Last not least (as written in an earlier mail) ESP-r has that "3d high definition" thing hidden somewhere ... therein, as far as I remember, you can descretisize (?) to your hearts content.

 

Hope that helps,

Best regards

Achim Geissler

BTW
Has anyone got info on how I'd use esp-r to calculate the thermal lag of a construction?
thanks
Pat
