2024.0
|
|
|
| TSD objects in a cloud database cannot be copied to another cloud database, a transportable database or an on-premise database.
|
2025.0
|
|
|
| TSD objects have gone through all routine development and internal testing. However, given their highly flexible nature, not all the possible combinations of available workflows have been directly tested. Therefore, when copying existing large TSD objects to a cloud database, editing existing data and re-running simulations, care should be taken to ensure datasets and results are as expected. Please
contact support if you experience any unexpected behaviour when using TSD objects in cloud databases.

Compilers for the cloud and on-premises simulation engines have been updated to meet security requirements and improve consistency between cloud and on-premise. This may cause differences in results for numerically sensitive models where the solution is on the edge of a mode (for example pumps on or off), oscillates between modes or has difficulty converging. This impacts all database versions. See
here for details.
