Material property curve export\import

[Telec]

Hi, is there a way to export the material curves from STKO, as we see them in the TEST phase? In order to be able to reconstruct them externally in excel.
Or similarly, is there a way to insert a material curves into STKO based on points entered by the user?
Thanks

Not in the current version, but it will be in the next one.
In the meantime, here is a workaround:
Replace these files

tester.zip

(18.16 KiB) Downloaded 259 times

in C:\Program Files\STKO\external_solvers\opensees\physical_properties\utils\tester
(You will need Admin privileges for this)

From now on, when you run a material Tester you will find and output.txt file in

• C:\Users\<Your PC User Name>\AppData\Local\ASDEA Software Technology\STKO\Tester1D (for uniaxial materials)
• C:\Users\<Your PC User Name>\AppData\Local\ASDEA Software Technology\STKO\TesterND (for ND materials)

Note: the AppData is a hidden directory, you need to show Hidden directories.
The columns in those files are:
1) percentage of the test (from 0 to 1)
2) strain (1 component for uniaxial, 3 or 6 for ND)
3) stress (1 component for uniaxial, 3 or 6 for ND)

Hi!
I had the previous version of the software and downloaded the new version (STKO-2.0.1). I couldnt obtain the output file when performing a material tester with none of the versions. I updated the files with the ones attached in this post and then the material tester created the file.
The date of the previous files were older than these new ones.

If you don't want the output file to be deleted automatically, you need to comment the highlighted line in the files
C:\Program Files\STKO\external_solvers\opensees\physical_properties\utils\tester\Tester1D.py (and TesterND.py for 3D materials)

I tried to follow this instruction, but it did not work work.
I have replace the file tester.zip. When I tried to test my material, there was not a output.txt in the directory.

I tried to follow this instruction, but it did not work work.

It should have worked.
However, now we have a better solution, it will be available in the next (V 2.0.2) STKO version.

In the meantime, I attach here 3 modified python files (zipped) to be extracted in:
C:\Program Files\STKO\external_solvers\opensees\physical_properties\utils\tester
replacing the existing ones (Tester1D.py, TesterND.py and GuiUtils.py)
