@MaxJPRey, would it be possible for you to address @mjc865's point here?
from pymapdl-reader.
@akaszynski Yes, we will work on a fix for this issue. Thanks for the notification.

@mjc865 can you share a minimum working example?

Hi @kiluam,
Looks like there's some work to do updating the legacy reader. I'm moving the issue to the legacy reader so we can track (and fix) it there.

Following up to this issue: 2021R2 result files can be read by ansys-mapdl-reader
, if this is failing for specific result files, I'll need a minimum working example and sample file (ideally small) to be able to debug the issue.

Maybe I can add some more information here: I investigated the issue and found out, that these new result files seem to use zlib compression at least for the element types. binary_reader.cpp does read the zlib flag but does not act on it in any way. Is there any documentation on this zlib compression available? I also try to get a minimal example. My current ones are more than 100MB.

Just as an update. So far I did not manage to get any small example because this zlib compression does seem to be activated only for big files. On the other hand, the zlib compression is fairly simple and the data read in each record just needs to be passed to zlib uncompress. I do not know how to handle all dependencies on C level here and it needs to be implemented in a lot of different but similar functions of binary_reader.cpp. One other way would be the use of the python zlib module that already implements everything needed in zlib.decompress. But still for my example which I got with and without compression active I could verify that all data matches exactly the uncompressed data if processed by zlib uncompress.

Hi @akaszynski , is this on the roadmap for a fix? I can probably generate an example file if you need one. We may need to move to a newer ANSYS release at some point in the near future and it would be nice to have the legacy reader working, since I use it to get the ANSYS results into MATLAB. I'm using the legacy reader because it does not require ANSYS to be installed on the computer. Thanks

@lars-bittrich which element types are activating the zlib compression? I can't seem to get an example using 2021R2 Workbench with SOLID186 and SOLID187 elements.

Adding @germa89 for visibility.
