SubscriberHello,
Â
Tiny bit of context since this is my first post here.
PhD student here with a supervisor who has trained me in APDL (no experience with workbench). We use APDL purely because we need extremely complex geometries for modelling gravitational wave detector suspensions.
Â
I'm studying next gen, cryogenic, detectors, so have moved from structural to thermal analysis of these suspensions.
Â
As I've been taught well (I hope), I'm starting on extremely simple models to conduct transient thermal analysis (we've just finished some simple steady-state models which match theory well).
Â
I started with an ANSYS worked example 12 for thermal analysis from the following link.(https://sites.ualberta.ca/~wmoussa/A...Cond/Print.pdf)
Â
All works out as expected AND when solving, I can view the graphical solution tracker to observe convergence.
Â
I'm slowly changing this model, one at a time to match geometries and conductivities I'm interested in. I was playing with it (remotely) with my supervisor and sure enough, we solved some solution and got the graphical display when solving.
Â
We decided a way forward, so I came back the next day after shutting down my laptop (Windows 10, Core i7 Dell Latitude 7490). When I came back and either tried previous models, new models or even repeated the above example (from complete scratch) I no longer get the graphical solver. I can't see the convergence solver (which I find extremely useful for my own models to see approximately when it reaches steady state/where the interesting physics is).
Â
Having plenty of experience with APDL on modern Windows machines, I know it can sometimes just be "funny" especially with graphics.
Â
I've tried setting /GST,ON,ON as well as ticking ON to Grph Solu Track in output ctrls (which always seems to be off by default and doesn't change with the former command line input).
Â
Any help appreciated and if you need more info, don't hesitate to ask!

Forum ModeratorThanks for the detailed question. Can you please try resetting the AppData as explained in this post and see if that helps, at all?

SubscriberSo this appeared to have made no difference. I'm wondering if it's simply a case of when it's a single thermal conductivity value the solver doesn't display. When I changed to a linear dependence, I seem to get the solution tracker up (but I got this up before the AppData wipe). However, it doesn't explain the disappearance of the solver still when it comes to repeating the example 12 above.
Â
It's not the end of the world, I can manage without it if it's inconsistent anyway but I appreciate your help - thank you!

Forum ModeratorI am bit confused now, you said that you were seeing the iterations before right and without changing anything, those disappeared? for a linear analysis with a direct solver, you won't see the convergence plot as it is solved in a single iteration.
