Glue and Touch contact on the same SOL 101 analysis.
Thank you both very much for your valuable answers ! dmapguru : Thank you very much for the clarification on the NLGLUE=1 message. I have run the analysis with the NLSTEP card as you told me. However, I did not find the NINCC parameter directly in HyperMesh, then I defined the NLSTEP entry as... -
Contact not Working on Nastran 2017
Thank you very much dmapguru. You solved my doubt in this paragraph : << I suspect you are looking at results in your post processor which is simply taking the single output displacement vector (that for S=0.0271) and animating it in multiple steps in a piecewise manner. There is only ONE... -
Glue and Touch contact on the same SOL 101 analysis.
Hello, I am conducting a static analysis in which I have both glue and touch contacts. My problem is to know how to actually define multiple contacts, and within it, the BCPARA entry where I define the LINCNT paramater to 1 for the glue contact, but I cannot define another BCPARA card with... -
Contact not Working on Nastran 2017
Thank you very much again dmapguru ! Your answer was very helpful and I could check the model with both S values that you provided. However, I still have a question. Why do we see, for instance, the contact forces since the first frame ? I mean I thought that we would start seeing the contact... -
Contact not Working on Nastran 2017
Hello DG, Thanks again for your help. We are still in the context of SOL 101. I will add some pictures below of what I tried to explain. I separated a considerably distance the plates to verify when the contact started (cf. image below, distance from midplane to midplane = 1.5mm). I repeat... -
Contact not Working on Nastran 2017
Thank you very much DG ! It was super useful what you said ! I have tried both methods and they work [smile]. I have a question concerning the case without LINCNT. I have contact from the beginning, it does not matter how much I separate the plates, from the very beginning, when the loaded one... -
Contact not Working on Nastran 2017
Hello everybody, I come to your help because I have tried everything and I cannot make a simple contact work on Nastran. As it is my first doing contacts, I thought about making a simple model, two thin plates. One fixed and the other with a pressure and fixed at the edges. The idea is to make... -
Addition of 1D elements reduces Buckling Factor
Hello ! I have one question. I'm studying buckling in a composite skin which has a large hole for a system. I have modeled the skin and a metal piece attached to the skin via fasteners (represented by RBE2). The metal piece has a grille on it, which I also modeled with 1D elements hoping that...- Emi.Cor
