The parsing of results from a .csv file could unexpectedly stop when an empty field was encountered.

Read Results – Scalar

META was unable to read fiber orientation tensor results on tetrahedral elements.

Decks – Adams

Unexpected termination could occur when reading ANSA Kinetics results.

Decks – Fe-Fatigue

The columns of CSV files would not be read correctly in case the previous ones contained null results.


Recorded sessions with Advanced Filter operations would not be reproduced correctly if extra colons (": ") were present in the filter (e.g. when searching for entities by name and the name included a colon).

Project Files & METADB

METADB files containing CONM2 elements could not be read correctly by 20.1.1, if saved in versions 20.0.1 - 20.0.3. In addition, METADB files containing CONM2 elements or having plots with plot attributes could not be read correctly by versions 20.0.1 - 20.0.3, if saved in versions 20.1.0 or 20.1.1.
