Editing material properties

Post by aease »

Hello.

I attempted to edit the material properties of "Solid Brick, extruded" (TUV - not IBP) from the WUFI database and wanted to ask whether there is a reason that the software does not let me change the vapour diffusion resistance factor? Everything else seems editable.

Many thanks in advance!

Hi Apostolos,

if the material is unlocked and the vapour diffusion resistance factor is still not editable, then there is an entire table for the moisture dependence of the resistance factor. Please have a look at the item "Water Vapour Diffusion Resistance Factor, moisture-dependent" in the list of Hygrothermal Functions of the material dialog.

In this case, the Diffusion Resistance Factor displayed in a single text field among the basic values only refers to the dry state, and this field is disabled to alert the user to the fact that there is more than just a single value.

Kind regards,
Thomas
