Doing a simulation with 750 iterations, the program stops with the message The analysis has stopped because the solver has exited unexpectedly. This comes around when iteration number is somewhere around 350-450. Several suggestions are given here:
one is to add a line is the cfdesign_flags.txt. Is this file in the program installation folder?

In 2015 the flags are controlled from the interface (Design Study Tools -> Flags) - I'll update that article.
I doubt this is the problem though. Are you running on a local drive and how does the model look when this occurs? Do the results appear sensible?
I run on the local hard drive. I can say exactly how it looks like. I happens when I activate auto force convection.
Hi,
We likely need to see your support (CFZ) file to troubleshoot this.
Thanks,

Thanks.
Your model looks overconstrained and I have a few comments/questions:
Thanks,

Thanks Jon for your comments and recommendations. I will change the model setting and try again.
The goal of analysis is to obtain information about temperature, wind speed and solar radiation on the external walls or in very close distance to them. The buildings are located in a cold climate. I attached a schematic section showing the existing environmental factors on the site, the red hatch is where I am interested to obtain information about. My idea has been to include significant environmental factors into simulation . For example, snow have effect on diffused solar radiation and soil temperature is under zero degree Celsius because of the long low temperature period.
Best regards,
