| Tony 2020-10-01 16:42:40 Hi Barry, I'm still in the process of checking the file because there does seem to be a modelling issue. However, my compliments because you have correctly assigned the Material characteristics to the wall material layers and the Window Frame elements too. The only thing missing at the moemnt is the Climate data (Assuming it's Omagh) in the General Data tab below. Please be patient while I check out why it's going out of Memory. Regards |

| Tony 2020-10-02 16:28:09 Hi Barry, sorry to keep you waiting. I've had a look at the file you sent and it seems to be modelled correctly. The only problem is that it's corrupt in a section of the data stream which causes the Thermal Bridge calculation to crash. I've sent it over to our Dev team for debugging and to see what's wrong and where. I'm afraid that you'll have to re-model it again if you're in a rush to carry on with your work. All I can say at this point is that the file was probably saved when one of those exception messages came up. |

| Tony 2020-10-05 17:41:29 Hi Barry, believe it or not but we were just taking a closer look at the file. I just discovered that the Thermal Bridge was modelled correctly but the scale must be wrong. I believe your intention was to model in mm but ended up modelling each part of the TB in meteres. You can immagine how large the Calculation becomes when taking in account such large dimensions. Can you please remodel it in mm or cm simply keeping your eye on the dynamic measurement values as you are tracing the various material layers? After that, TherMus will surely be able to provide a full Thermal Bridge calculation and the relating report sheet too. Sorry for the delay but I only just noticed! Regards |

| User_1176156 2020-10-06 13:25:17 Tony, How do you set scale when starting new model, also can you advise what this fatal error warning means. 1016: Section length is ZERO The section length for the linear thermal transmittance calculation is zero Solution Verify that the adiabatic surface doesn't cross a structure that adjoins an internal area In such case, define the structure's length to which the linear thermal transmittance is assigned. You have chosen a comparison length on a wall that does not separate INTERNAL and EXTERNAL environments Set the length to zero or correctthe boundaries You have chosen a comparison length on a wall that separates INTERNAL and EXTERNAL environments Vary the length or correct the boundaries. |

| Tony 2020-10-06 14:45:22 Hi Barry, Default measurement system is in meters. Any reference to other thermo-physical characteristics are shown in the panel on the right. Normally all in [mm]. With the Errors you are receiving during the calculation, try setting the BOUNDARY type to Internal or External and run the calculation to see what or if any errors remain. If you have elements that are in contact with the ground, we normally set it to "Adiabatic" and then define a boundary calculation section length. However let me know how it goes and if necessary send me the correctly modelled file over for a quick check. Regards |

| User_1176156 2020-10-06 14:46:16 Tony, Can you advise that within the TerMus software thermal bridge calculation are psi values calculated and can this detail be included in technical report. |
Tony
| Tony 2020-10-06 15:17:23 I've sent you an example Report for you to look at. All values are shown according to EN ISO standards. Regards |

| User_1176156 2020-10-26 13:08:37 635529_1603713941_model_file.zip Hi, would you be able to check attached file and advise if modelled correctly and boundaries, convective coefficient and material are assigned correctly, thanks. Barry |

| Tony 2020-10-26 14:12:18 Hi Barry! Great work - Absolutely no issues whatsoever. Diagnostics is clear and no modelling errors. Report is Complete and all diagrams illustrated correctly. Best Regards |

| User_1176156 2020-10-27 15:30:13 Thanks Tony, Question, when modelling a window head were actual wall measurement from window head to ceiling is 300-400mm, in the model do you need to extend wall to 1000mm for calculation or leave it as per actual. Regards Barry |
Tony
| Tony 2020-10-27 16:14:47 For a more precise calculation model it's a good idea to extend to ceiling. Of course it depends if you need to concentrate on a specific Thermal Bridge - Mould Check Area. |
Tony
| Tony 2020-12-16 14:32:56 The calculation solution shows that the linear thermal transmittance assumes a negative value at exterior corners and a positive value at interior corners. This is actually quite a normal case. I've noticed that some materials also result to have a negative transmittance. Can you please check your material settings in General Data Tab also. Let me know if you still need help. I will scale the issue to our Dev Team however. Regards |

| Tony 2021-01-12 10:30:31 Hi, Can you send over the fies that aren't opening? Zip and attach here. If software is inststalled and working correctly, there shouldn't be any issues with opening your previous files at all. Regards |
