I am trying to model 12.7 cm wide vertical blinds using WindowMaterial:Blind:EquivalentLayer. When I do so I get the following errors:
* Severe * Out of range value Numeric Field#1 (Slat Width), value=0.12700, range={>0 and <=0.025}, in WINDOWMATERIAL:BLIND:EQUIVALENTLAYER=WMTEUQL_BLND_KINDV_RF80_T02_A18_RB45 * Severe * Out of range value Numeric Field#2 (Slat Separation), value=0.12700, range={>0 and <=0.025}, in WINDOWMATERIAL:BLIND:EQUIVALENTLAYER=WMTEUQL_BLND_KINDV_RF80_T02_A18
The input should be in meters. It seems a bit strange that the slat width would be limited to a maximum of 2.5 cm. Wider products are quite common and for vertical blind a slat width as small as 2.5 cm doesn't exist. The input output reference also state that 2.54 cm should be the default value.
I am using EP 8.5. I have also tried updating to 9.0 but this still gave the same error. My WindowMaterial:Blind:EquivalentLayer object (I am aware I am omitting visible properties. I am not interested in these and the exmple IDF shows they are not required):
