Hello Hugo,
I have investigated a little more in detail the problem of accessing large XDB file with FeResPost 32bits libraries.
What I wrote in my last message is not totally correct. In earlier versions of FeResPost, the access to large XDB (or Samcef FAC) files was possible. But it is no longer possible with recent versions of FeResPost. The reason for this, is that I switched to an newer version of GNU C++ compiler. And the reason for this change is that I needed a more recent version to compiler libraries for recent versions of ruby (versions >= 2.4*).
It seems that 32bits GNU standard library no longer supports the random access to files larger than 2Gb. (See the link below.)
This may be in line with C++ specifications, but I consider it as a regression and a shame.
As most computers are today 64 bits computers, this is in general not a huge problem i. I see one exception however: when the COM component is used from 32 bits excel, it may be interesting to access XDB files larger than 2Gb. (In my compoany, we suse 32bits Microsoft Office.) Therefore, I decided to produce Windows 32 bits binaries with version 3.4.5 of GNU compiler. These are now distributed with other binaries of version 4.5.6.( Of course no FeResPost binaries are produced for ruby versions >= 2.4*.)
Future versions of the User Manual will contain information about these problems.
Regards,
Renaud
