Question:

Were there any changes to the format of the results databases (in particular the *.RTH and *.RST file) between 8.0 and 9.0?


Answer:

There was a major change to the results files at release 9.0; the entire file now uses 64 bit pointers. The addition of 64 bit pointers to the solution part of the results files at release 5.5 allowed for files larger than 2 Gb without file splitting and was believed, at the time, to be all that was required. It was assumed at the time that the front end of the file that contains the geometry would not need long pointers. That is the change at 9.0. If you are reading results files, it will be necessary to convert the pointers to long integer form. If you are writing results files, setting the release identifier to 8.0 will solve the problem in the short term. In the long term it will likely become necessary to convert the writing program to long integers.

I am attaching 3 files for you. One identifies the differences. The other 2 are the documentation files for the results files for release 8.0 and release 9.0

The second change is the format of the nodes. Previously, the node record was a single record that contained all of the nodes and their coordinates. Beginning at 9.0, the nodes are written individually so the number of node records increased from 1 to the number of nodes. This is also because of the size of the geometry is now unlimited.
