<div style="font: normal undefined undefined; color:undefined;">I am trying to get a model of a simple log cabin to match measured data - I have managed reasonably well with the temperatures but the modelled relative humidity swings a lot more than the measured values. Given that the construction is untreated bare fir logs then there must be a lot of moisture adsorption going on which damps out the R.H. swings from the considerable infiltration.<div><br></div><div>I have been looking for a guide to how to set up a moisture network (I only have one zone!) - looking at the Synopsis of the model House with moisture modelling in living room.</div><div><br></div><div>I suppose the key is in option k "Adaptive gridding and moisture" in the Zone Composition menu however the help doesn't seem to get beyond option "c" and this is option.</div><div> </div><div>And then the help on selecting a zone is: </div><div> </div><div>"There are four adaptive gridding files which must be specified</div><div>for each zone to which such gridding is to be applied.</div><div> </div><div> The moisture file holds moisture transport data for nodes.</div><div> </div><div> The 3D control volumes file defines...<< ? >></div><div> </div><div> The 3D control volumes connections file defines...<< ? >></div><div> </div><div> The 3D nodes coordinates file defines...<< ? >></div><div> </div><div> The 3D nodes temperatures file defines...<< ? >></div><div> </div><div>To proceed with adaptive gridding you first have to...</div><div> << instructions to be added >></div><div> </div><div>Check documentation for more information.
