it is necessary to give the thickness and the pressure value
I prefer use z88os
I use triangle to generate mesh
I write a small python program "b18h.py" to generate this file z88i1 z88i2, z88i5, z88elp, z88mat, z88man
I took as a test, a plate with a hole "plan2d"
I tested the program with plate no. 18 and shell no. 24
Apparently the pressure is not considered
With the software RDM6 http://iut.univ-lemans.fr/ydlogi/rdm_version_6.html , I get these results. I send you my files
with RDM6, z88os flat 18, shell 24 z88os, plan2d

The file z88i5.txt was empty. We included a version that works with your project and yields the "same" results as your reference (bear in mind we used a slightly different material). Hint: you can basically use the coi-part of the i1 and swap the element type with the pressure value and put it all in one line.
The structure definition was wrong. Shell 24 needs to be in 3d and each node has 6 degrees of freedom and also 3 coordinates. So the beginning of the shell24 i1 should look like this:
3 1633 781 9798 0 #AURORA_V2
1 6 +0.000000000000E+000 +0.000000000000E+000 0.0
2 6 +0.000000000000E+000 +1.000000000000E+003 0.0
We hope this helps.

number of the element parameters
element from element to thichness pressure
It don't follow these guidelines
I put the files with corrections according to your recommendations
Thank you very much for your help

your last post is not very clear on whether you managed to solve the problem.
A big thank for your remarks quality.
I use elements shell type 24
When I launch the solver Z88R, I can't obtain a result.

z88mat.txt number of material data 1 -> 3
z88elp.txt number of element parameters 1 -> 2
but I still have a mistake for the solver
this cannot work.
Your structure is invalid, there are overlapping nodes which lead to the elements not being connected and thus your structure is underconstrained -> solver error.
Look at the picture attached below (from Z88Aurora, where I imported your structure for better visualization and Excel to find numbers of the overlapping nodes).
# of nodes your structure has: 48
# of nodes your structure needs: 35 (13 too much)
Overlapping nodes (-> only keep one node per group):
6, 17, 23, 33, 39
Thank you for your help.
I made a new mesh according to your advice.
Solver works, but the result does not seem consistent.
I can not find the error. (See files)

same problem: overlapping nodes.

Effectively, I made the same mistake.
now I use gmsh instead of triangle to make the mesh
Here is the result

why don't you check for yourself? We can't play this game forever...
