When I set a lightweight building will use PCM, due to the use of ConductionFiniteDifference, appear the following error
“1. ** Severe ** InitialInitHeatBalFiniteDiff: Found Material that is too thin and/or too highly conductive, material name = COLOR STEEL PLATE”
Can it be successfully run by modifying nodes in EP Lauch, etc.? Or there are other methods regarding HB [for example, now, if the value of the total structure of the wall is calculated, no error will be reported]
hi,@ZoeySwift
The conclusion in your report is already quite clear,The thermal conductivity of the material you are currently using is too high and the thickness is too small. If you don’t adopt this report, you can create a composite color steel plate material using Material. For example, you can mix the insulation (or heat insulation) material with this high thermal conductivity color steel plate material. This will also allow you to obtain a more accurate calculation result.
best.
