System Load Calculations in PRM not working

[tabbas]

I am trying to run an ASHRAE 90.1.2007 and have got to the step where i calculate system loads. It doesn't work. I have found that the baseline models are ok but the proposed model HVAC file clearly has issues. I get about a thousand warnings popping up that say:

assertion 'id.empty()' failed.

Anyone had this issue before?

Hi, I'm having that problem now.

Some times, other error messages appear, like: " Apache terminated unexpectedly" ... It is very frustrating because there is no apparent error. I'm using the IES 2017 version.

Did you solve your problem?

Same here. I got this error message "Apache terminated unexpectedly" consistently after I updated the IES VE to the latest version released on 27 Sep 2017.

Any help?

Hi,

This error can come up any time Apache encounters a problem during the calculations so there is no one single cause. Having said that we did identify and resolve an issue in VE 2017 Feature Pack 3 (2017.3.0.0) that was triggering this message for lots of varied projects so download that from our website as soon as possible and if the issue persists then let us know and we'll contact to get your project from you for testing.
