2022-08-31 08:58:26 -0500 marked best answer EnergyPlus setting heat transfer algorithm for constructions - leads to fatal error

Hi there,

does anyone have experience in setting the heat transfer algorithm of selected constructions? According to the IO-Manual, I can set the global behaviour via

HeatBalanceAlgorithm, ConductionTransferFunction, 200; !- Algorithm, Surface Temperature Upper Limit {C}

and can then change this for selected constructions like this,

SurfaceProperty:HeatTransferAlgorithm:Construction, BO05Override, ConductionFiniteDifference, BO05; !- Name, Algorithm, Construction Name

Seems easy & straightforward. However, I then get a fatal error when trying to run the simulation telling me that "InitialInitHeatBalFiniteDiff: Found Material that is too thin and/or too highly conductive ..." which gives a material name that is not part of the construction addressed.

Any ideas welcome. Best Achim
