NL analysis with NLPCI, how to output more than one load factors
Hi there,
i try to set up a non linear analysis with large displacement and nonlinear material (hyperelastic). I have much trouble to get a convergent solution. Now i found out that it works with NLPCI and CRIS or RIKS. But now in the post processing i only get two simulations steps outputted, zero and the maximum displacement. I want to plota load-displacement curve, therefore i need more simulation steps. How could i achive this?
Thank you very much for your help

you need to rquest intermediate results by creating a load input of type NLOUT, and request this inside your loadstep.
Depending on your settings you will get the intermediary outputs.
thank you i have already done this. But it doesn't work.
Altair Employeethank you i have already done this. But it doesn't work.
can you try the attached file?
Are you sure you're lauching the post-processing in HV, in 'Transient Mode'?

thank you. Your files are working. I attach my files. In this files i don't use Arc length method because i have to enforce a displacement. May you can help me with this problem. May i don't need RIKS/CRIS... I have trouble to get convergence solution and tried already so much things. But nothing helped.
I want to simulate a hyperelastic part with large deformations and contact... Because of possible instability problems i thought i have to use riks/cris.
