Restart stuck at first timestep

[fcurow]

To whom it may concern,

Have you guys experienced restarting an fds run and it just gets stuck on the first timestep? We have waited a day for it to progress (restarted the case from time zero in parallel).

Best Regards,

I am a bit confused. If you are starting from T=0, do you need the restart?

Please attach you input file and we will test it. Thanks

OK, please send us the file.

It's project sensitive, I can't share it. Any specific lines I should look out for?

What version of FDS are you using? Since we started adding RESTART verification cases some time back, I have noticed a significant reduction in RESTART problems. Please make sure you are using the latest code. Beyond this, we would need some kind of test to debug. Try to reproduce the problem in some non-sensitive case.

version 6.7.5

Go the FDS Release Notes and search on "restart". You will see many issues addressed between 6.7.5 (2020) and now. Please try with the latest code and let us know. Thanks
