Description

The tddft run aborts after 100 iterations with the message:
"qball: SlaterDet.cc:269: void SlaterDet::resize(const UnitCell &, const UnitCell &, double, int): Assertion `maxlocal != 0' failed."

The files and restart folder are also not saved. How can I fix this please.

Research direction

Start by inspecting the assertion at SlaterDet.cc:269 and the tddft run that aborts after 100 iterations. Reproduce the failure if possible, then trace why maxlocal becomes zero and verify that the calculation completes without the assertion while saving the files and restart folder.
