Unable to read generated inp file with cohesive interface in abaqus about neper

[rquey]

Does this happen with the latest version? The Abaqus output was fixed in 810d6a5.

Yes

Your Neper commands are correct, but there seems to be a problem with the format of the inp file. Could you try to find what it is by editing the file? You could also compare the file with the one generated with -interface continuous.

I tried to manually check the .inp file. Inside the *Element, type=CPE3 section, there is a line called C2D4. Some elements are listed in it. I'm pasting the entire section here. Kindly have a look.

This looks fine. Because when i try to edit the C2D4 line in my inp file to *Element, type=C2D4, abaqus throws another error saying
"element type C2D4 not supported."
Thus, can you please tell me what the problem might be?
I compiled the latest version of neper today itself.

[rquey]

Please post your file and provide your neper version.

[ombrophile]

Kindly have a look at the following file
n2-2dCZM.inp.txt

I cloned the neper source from github and compiled it. When issuing neper -V, it shows version 3.0.1.

[rquey]

Use the devel branch. The current version is 3.0.2-62.

[ombrophile]

I'll try that.

Sir,
The program is working fine now and the abaqus inp file it has generated seems to be working.
Thanks for the help.
