Hi Lorenzo, It sounds like the data isn't being written to full precision in your case. This is surprising to me, so I'd definitely like to look into this some more.
I suggest two options: 1. Make a minimal test case based on one of the RB examples in libMesh that reproduces your issue. Then I can run that myself and look into it. I suggest you first check if you can reproduce the issue in a non-EIM case to check whether this issue is related to EIM or not. 2. Update to using RBDataSerialization. To do this you'll need to configure libMesh wtih capnproto <http://It sou This should not happen. If you can come up with a test case that reproduces this behavior, then I can look at it more carefully. It would also be good to isolate whether the issue is related to EIM or not.>. Switching to this approach may just fix your issue. If it doesn't then it will still be helpful since we can directly read the capnproto binary data using the "capnp" tool and check if it matches the data that we expect.
