Re: 5-cm ventilated air gap
Hello, In order to have an idea for the temperature difference over a air gap you can make a simulation with standard properties first and se what differences you have. Its only a guess but better than nothing. For a ventilated air gap you can use the source 'Air exchange with ambient air..'. Here y...

Re: Mould growth risk: Isopleth model results
Ok, there is a bug in the calculation algorithm for the mould risk times in isopleth model. I will fix it and send you a link to the new version by email. I will also put the new version on our server for download as soon as possible.

Re: Mould growth risk: Isopleth model results
Hello,
Nothing is missing and I can run the calculation. But my isopleth charts look different. Do you used averaging? Do you have limited the isoplet points to a certain time period?

Re: Mould growth risk: Isopleth model results
Hello,
May you can attach also the project file. I would like to recalculate the results in order to evaluate what happens here.

Re: Adding a new Material in the Database
Hello,
The model parameter should only be used in the case you have your model for moisture storage function. If you create your storage function by data sets you don't need this sections.

Re: Anisotropic modelling
Hello, The anisotropic modelling is not fully implemented. We don't have a tutorial and also no possibilities for setting properties in GUI. In order to set the directions you need to set a parameter in the assignment area of the project file. Here an example: <Assignment type="Material" l...

Re: calculating surface convective heat transfer coefficient
Hello, It depends on the selected kind. For kind 'Exchange coefficient', the exchange coefficient is constant. For the kind 'Boundary layer' we use the following function: h = h0 + c * v ^ e v is the air velocity. h0, c and e are coefficients. Here is a picture of the corresponding boundary conditio...

Re: The unit conversion in the initial conditions of Delphin model
Hello,
Salt mass density means salt crystals. kg/m3 means kg salt crystals per m3 materials. This unit cannot be converted into molality
