UTCI recipe error - The process cannot access the file because it is being used by another process

Hi LBT Community,

I’ve been running a series of UTCI maps both on my laptop and on an analysis PC, both originally working well. However, I’ve now started getting an error on the analysis PC (I believe it’s a VM), while my laptop is still running the exact same script fine.
UTCI_example_comfort_under_a_tree_with_visualisation_tools_test_fromVM.gh (208.1 KB)

Here’s the error message from the VM, also saved full report out as text file
UTCI_Error.txt (530.2 KB)

Runtime error (PythonException): The recipe failed to run with the following summary:

This progress looks :frowning: because there were failed tasks

Use the report_out attribute of recipe settings to see a full report.

Any thoughts on why this is happening would be hugely appreciated


I’m on UK hours and off on leave from end of today, back on Monday - but I’ll check in for any replies then. Thanks in advance

I encountered the excatly same problem in the same example files and I found log files for the calculating process.

This can happen if you have one of the files in the simulation folder open in another program. For example, if you open a CSV file in Excel, Windows will lock the file in the simulation folder and not let you delete it. So make sure all files in the simulation folder are closed before running the simulation. If that fails, you can try manually deleting the simulation folder and that should give you some insight into the file that you have open.

@DavidLuo ,

Looking at your log file, your issue is different. Here is the real error from your log file:

[09:52:54.571759 ERROR] D:\OSN\src\model\PlanarSurface.cpp@629 : Cannot create a surface with vertices [[0.002, 0.002, 0], [0.002, 0, 0], [0.004, 0, 0], [0.004, 0.002, 0]]

It looks like the units of your Rhino model are not correct as you are trying to simulate a surface that is 4 millimeters by 2 millimeters.

Thanks a lot! That is the problem. :grinning:

Happened to me too, units were in feet, didn’t we get a prompt in the past about the wrong unit being used ?
