DIFFERENCES BETWEEN V2.1 and V2.0

Version 2.1 has been modified to conform with recommended F90 programming practices, specifically with regard to the use of modules and interface blocks. The changes are,

• the fundamental common blocks previously declared in header files such as physicaldata.fh have now been replaced with modules.
• all preprocessor variables which the user needs to define have been collected into a single header file for convenience.
• a module has been declared which defines interface blocks for all the paramesh routines.
• bug fixes for all bugs which have been reported to us since the release of V2.0.

It should be emphasized that V2.1 will support any applications which ran using V2.0, with almost no modification to the application source code. The required modifications, all of which are very minor, are summarized below.

Modification Steps

1.
The header files physicaldata.fh, tree.fh and workspace.fh have been replaced by modules. For example, to use the module which replaces physicaldata.fh you must replace the line #include "physicaldata.fh" in your application files with the line use physicaldata and this line needs to be repositioned with any other `use' statements in accordance with the F90 rules for the placement of `use' statements. Similarily #include "tree.fh" is replaced by use tree and #include "workspace.fh" is replaced by use workspace

2.


The makefile templates which were provide in versions 1.0 and 2.0 used the standard make. Since this functions differently on different platforms, we have replaced these with a GNU make template. This requires that you have GNUmake installed on your system. The GNUmake template compiles all PARAMESH modules and source files, placing the .mod and .o files in a sub-directory called paramesh_objs.
