Hi,

When I load the TFM MFIX tutorial

I cannot change the parameters of the inlet_velocity keyframe (steps, linear, what property is read) etc. It appeared once and then never again in all tests I tried. I had to manually change them in *.mfx. Should be a minor fix but an useful one :). I added the same temporal BC in another sim, and had the same issue. Best, E.

Sorry, the keyframe pane is broken, we will fix in the next release, thanks for reporting the bug!

Thanks Eric. This will be fixed in 25.2, in the meanwhile it’s a 1-line fix if you want to patch the file yourself.

The file is:
$CONDA_PREFIX/lib/python3.12/site-packages/mfixgui/keyframe.py

diff --git a/mfixgui/keyframe.py b/mfixgui/keyframe.py
index bb81f82e3..10e83922e 100644
--- a/mfixgui/keyframe.py
+++ b/mfixgui/keyframe.py
@@ -130,6 +130,7 @@ class Keyframe:
         # Autoselect if only 1 row
         if row is None and tw.rowCount() == 1:
             row = 0
+            self.in_setup_keyframe = False
             tw.selectRow(row)
             return

You can either use the patch utility or just open the file in an editor and add that one line.

Sorry for the trouble,
