hello
i have this very strange error with shell element on 16.5 and 17 linux version of code_aster
it happens on the first TRIA3 element encountered whatever the type of mesh .med, .mail
it does not seems to happen on QUAD element
my first guess is that it fails in building the stiffness matrix of the element

if i run the same files on 14.6 and 15.2 version it runs smoothly
further note: some files downloaded from this forum seem to run OK on window$ version but fail on my linux version
