HI,I am running a simulation on Bentley Hevacomp V8i.I have created the roof on the Fabric Data Tab. I then click on the MAT Tab. Here i select new project, exposed roof ect. Then under the roof data tab, when I try to add a layer (where i can specify thermal properties of each layer) i am given a "run-time Error '53'" and the porgram closes. Am I taking the right steps etc.?Do you have a tutorial available?Please respond with urgency.Thanks and Kind RegardsJack
Hello Jack,
This is a known issue that can be resolved using the instructions in the Wiki below. You need to download some files and unzip them to your machine.
Version 26 - Run Time Error 53 in MAT after installation
Please let us know that this resolves your issue.

Thanks,
That seems to have done the trick.
1 more question.
Do you know how to convert the vapour resistivity value from a dimensionless Mu-Value to GNs/kgm?
Thanks
Jack
Hi Jack,
To the best of my knowledge you would divide by the vapour permeability of air, 0.2.
However I would advise confirming this yourself, BS 5250: 2002 'Code of Practice for the control of condensation in buildings' should provide all necessary info if required.
