Rahma,
I’m just curious – what material/construction do you have in mind?
In general, you may do the following:
- Write a new component (so-called Type) which models the heat transfer in the construction as you want.
- Couple the Type to Type 56 as other construction models e.g. TRNSYS Nostandard Type 399 (finite difference approach).
However, as Jeff mentioned this isn’t an easy task.

Betreff: Re: [TRNSYS-users] PROGRAMMING in transys
thank you for your response
I want to reprogram the heat transfer equations in the wall because they give non-exact results for certain new construction materials
Rahma,
I can’t honestly think of anything that would be harder to do in TRNSYS for a beginner - heck even an expert.
May I ask why you would want to re-work the algorithm that does the heat transfer in the walls?
