The student version R2023 v1 uses an extremely small font. I fixed most (but not all) of this following the recommendation I found here: https://www.cfd-online.com/Forums/ansys/184634-work-bench-gui-very-small-font.html
This fixed everything except for "mechanical", i.e. I start up a static structural analysis, import some simple geometry, and then select "model" command to apply loads and create a mesh. Unfortunately the modeler package goes back to the "tiny font" mode. The panel at left is normal size, but the menus at the top are unreadable and step on each other.
Interestingly, both Discovery and SpaceClaim use normal fonts while DesignModeler uses the tiny font and is unusable.
I'm running Windows 11 on my Lenovo laptop, Intel i7 processor.
