Re: [LBNL-THERM] memory allocation error in ConRad

[Robin Mitchell]

I suspect that your model is more complicated than THERM can handle, hence reducing the EEN allows it to simulate.

If you want me to look at the files to see if they can be easily simplified to keep the EEN at 10%, email them to me and I will take a look.

Hi,

I am currently modelling a few façade details on Therm 7.3 and I have had the following error a few times : “memory allocation error in ConRad”. I had a look on this forum and didn't find any answer (but maybe I didn't look properly?), then I checked on the internet and found this topic https://www.aecb.net/forum/index.php?topic=3406.0. Therefor I just tried to change the Maximum % Energy Error Norm as suggested, but the default value is 10% already. I does work at 11% but I was wondering if the accuracy of the U-Values was still good? It seems that most people are doing the calculation with a 2 to 5% Maximum % Energy Error Norm. Would you advise to keep the 11% Energy Error Norm or just simplify the model?

Also, what Maximum % Energy Error Norm is in agreement with the australian requirements?

 

Thank you in advance for your answer.

 

Kind regards,
