This section describes the operational changes, the procedural changes (actions that have to be done differently in this release to get an outcome available in previous releases), and the support changes (functionality that is no longer supported) in Release 14.0 of CFD-Post.

Operational Changes

In Release 13.0, forces at interfaces or cut planes were approximated by adding pressure and mass flow force. However, this calculation will not balance the forces at walls. Release 14.0 has a more accurate calculation of the approximate force, which is derived by subtracting the mass flow force from the pressure force at interfaces and cut planes.

In FLUENT there is an option to have additional post-processing variables written to FLUENT DAT files. There is a change in behavior in the reading of variables from FLUENT files. In Release 13, when selecting to output additional variables in a DAT file in FLUENT (via the Data File Quantities panel), you had to choose only the variables that were not automatically output to DAT file. Otherwise, the chosen variable would show up in CFD-Post with a numerical suffix (for example, you will see 'Velocity 1' in addition to 'Velocity'). As an alternative, you could use the CDAT file format to specify exactly which variables to output to CFD-Post. As of Release 14, when a variable is written to the user-specified section of a DAT file, CFD-Post will check to see if the same variable is available in the basic section of the DAT file. If so, the variable from the basic section will not be read in CFD-Post, only the variables from the user-specified section of the DAT file will be read.

Reading of 13.0 FLUENT cases that have multi-configuration information can fail in CFD-Post 14.0. A workaround is to set the FLUENT_MULTICONFIG_OFF=1 environment variable before running CFD-Post.
