Problem with read_med

[Dzifa Kudawoo]

Hi all,,

I try to convert a ".med" file to ".h5m" file but it seems that there is a little trouble with the read_med binary. Indeed, I use salome-meca 2018 which use the med version 3.3.0 by default see below the error.

I also try to the following mesh version: 3.0, 3.1,3.2 but read_med seems to not work.

The command that I use for the meshv3.3 is

$ read_med mesh.med  -meshsets_config config_brick.cfg

Is that correct ?

Sorry, I just modify slightly the command that I use:

$ read_med mesh.med

Result:

meshV3.0,1,2 It works and it generated the out.h%m

meshV3.3 It does not work

Hello,

Yes, when med reader when implemented into MoFEM version 3.3 was not available. As you can see here:

Reading MED file V3.3.1 using MED library V3.2.0

Our med lib is V3.2.0. At some point we will need update med library. 

Can you use write to older version of med format or it is critical problem?

Kind regards,

Lukasz

As a note, new version is available as pointed here:

https://www.salome-platform.org/forum/forum_11/527729477

So it should be only a bit of work to update all that new med is automatically downloaded and compiled with mofem. However, you never know what else has been changed.

YESS. It is not an obstacle for med since I can save the mesh in a previous format. Just it is good to know for the future.
