[esp-r] Res: Problems running validation sets on esp-r

Fri Oct 2 12:40:58 BST 2009

Dear Jon

Thanks for your answer. I checked the partition where /tmp is placed and it has 21 Gb of free space. I noticed that such problem begins after running any validation set for the first time. So I have to restart ESP-r 11.7 again to run another set. I am still concerned about the differences between the current simulation results and the previous ones from ESP_1993 (they 're also found for other ASHRAE 140 validation sets and partially for CEN/ISO ones). Did you observe any difference between the results of your tests and those from ESP_1993? I am afraid there is some compilation issue I am missing, any hint?

Clodoaldo.

Assunto: RE: [esp-r]  Problems running validation sets on esp-r

I am currently running "All the tests" in the BESTEST suite and thus far what
I have noticed is that model 960 is complaining about an issue in a control
file.  (This is with a cutting edge version of ESP-r rather than the
standard version).

One issue is that the process places files in the /tmp folder.  If your available
disk space is limited then the process could easily fail.

Subject: [esp-r]  Problems running validation sets on esp-r

Dear ESP-r users,

I am experiencing problems running validation sets on ESP-r 11.7. After running the 960 (high mass sensitivity) validation set of the ASHRAE 140 for the first time, ESP-r returns the following:

Selected tests from group High mass basic sensitivity tests
900-600
Test: High mass basic sensitivity tests - 900-600
Error opening results data file;
returning to main menu.
Output description  Simulation     Range    Minimum      Maximum      Previous
                      result       check     bound        bound        result*
delta Annual_heating -4377.        outside  -3837.       -3126.       -3126.
delta Annual_cooling 6874.         outside  3833.        4624.        4005.
delta Peak_heating   -3.688        outside  -0.5870      -0.4140      -0.5870
delta Peak_cooling   6.531         outside  2.810        3.355        3.306
*previous results from: ESP_1993
--------------------------------------------

The simulation results are outside the ranges and are worse than the previous results form ESP_1993. If I try to run the same validation set again or any other set, ESP returns the following in the terminal:

closing export file: /tmp/900.dat
Generating specified output(s)...done.
Error opening results data file;
returning to main menu.

I've compiled ESP-r with gcc-3.4.6, gcc-4.1.2 and gcc-4.3 on Ubuntu 9.04 and the problem still persists.

Any help would be appreciated.
