Thread-topic: Error generation shading matrix

Dear Dani,

a large number of windows may cause memory problems.

For the upcoming release of Trnsys 18 we have resolved this problem for the generation of shading matrices.

If you use the Trnsys version 18.04.0001 we may send you an update that fixes the problem.

If you are interested in using the improved routines for your project, please write an email to hotline@transsolar.com

Kind regards,

Marion

Betreff: [TRNSYS-users] Error generation shading matrix

Dear Trnsys users,

I am having a problem with the generation of the shading matrix for the attached building model. I already simplified the model reducing the windows numbers and trying to avoid to draw the windows too close to the wall borders. TrnBuild is not yet able to generate the shading matrix. Should I reduce more the window numbers (at the moment there are approx. 120 windows)?

Thanks and have a nice day.
