Greetings,
I read through the manual for Membrane node and found that "Include Geometric Nonlinearity" is necessary to be checked in the Study Step. This is to include the prestress specified in "Initial Stress and Strain" node.
However, after turning it on, the study could not converge as the maximum Newton iterations of 25 has been reached.
The 3D model involves a 0.5 mm thick rubber membrane fixed along its edges for acoustic studies.
Hope someone can advise. Thank you.
