So, the simulation seems to run successfully, meaning this is not an issue with FEPX. The error clearly occurs when you run a Neper (-S) command.

You state you are using Neper v4, but your terminal output shows:

Info : Version 3.5.3-209-neper-fepx

I suspect this is a version issue, and perhaps due to bad linking or pathing, if you have installed a newer version. Can you please try running using v4?

This is not sufficient information. Please provide your commands and all of the terminal output.

First I ran runexample.sh in the case folder (1_uniaxial), and the calculation was successfully completed. But when I run postprocess.sh, the command line terminal prompts the following information:

This is not all of the terminal output. Please provide the FEPX terminal output, as it contains helpful information (not only whether it worked or not, but also - simply - the version you used).

Thanks a lot for your reply.

My operating system is Ubuntu 20.04.
The version of FEPX is Version 1.1.1
The version of NEPER is 4.0.0

The following is FEPX terminal output:

Info : Version 3.5.3-209-neper-fepx

I think this is actually what the very first version 4 (4.0.0) was printing (the version number had not been not updated properly).

Anyway, please try again with the most recent Neper and FEPX versions.

mkasemer avatar mkasemer commented on July 24, 2024

@fzw9381 - was the resolved when you used the most up to date version of Neper?

acmelab-ua avatar acmelab-ua commented on July 24, 2024

I am closing this issue as it relates to post-processing rather than FEPX.
