Re: THE YELLOW SHELL-MARINE

Mr. Frisch

Thank you very much for your interest.

I've already emailed you the z88i1.txt file of the "yellow shell-marine". I'll be waiting for your opinion.

Best regards.

THE YELLOW SHELL-MARINE

Aurora Team In order to get more resources for making FEA with AURORA, I developed a new meshing procedure. This time is for get E24 shells from IGES or STEP files, that´s to say from any CAD system. I attach some images that show the results. I'm rather sure that the method works but I'd like to se...

Re: improving meshes

Hi, Frans

You say that "Importing is a bit tricky i don't know how "to compile" the cascade step. importer function with the netgen."

Just a question. When you installed NETGEN, did you installed also the "Open Cascade kernel"?

best regards

Re: improving meshes

Tim I suppose that you, as I, tried unsuccessfully to install Netgen 5.0 by compiling the binaries files. At http://sourceforge.net/projects/netgen-mesher/fles/netgen-mesher/5.0/ there are Windows Installers for 32 and 64 bits. I tried the 32 bits one and it works fine but... at the new Netgen versi...

Re: Netzstruktur unregelmäßig

TAH1712 I’m glad to see that the procedure I described is useful for another Z88AURORA user. I imagine that you experienced the same that I: overcome the meshing barrier changed my relationship with FEA. Regarding the procedure, I'm sure you have already found ways to improve it. I myself have been ...

Re: Non Linear Analysis - Hinge example

Aurora Team:

I apologize for pointing out a malfunction of the Z Limit tool. Actually the problem is in the way I set my graphics card to run Z88 AURORA (in order to see round picking points). Best regards.

Re: Non Linear Analysis - Hinge example

Aurora Team: Concerning similar issues, check please the Z Limit tool. Here it seems to be also impossible to restore the initial view (un-clipped) and the little brush does not help. But, IMHO, these are not so important matters as the fact that stresses in NLA are exposed just at the Gauss Points,...

Finally I could discover the utility of the little brush. It works fine. Thanks a lot.

Re: Non Linear Analysis - Hinge example

Dear Mr. Wehmann, thank you very much for your reply. Although in this case the results for Stresses at Gauss Points of the LA @ 615 000 N are quite similar to the NLA @ 900 000 N, I share with you the warnings about the risks of a simple extrapolation. I don't fully understand when you refer to &qu...

Re: Non Linear Analysis - Hinge example

Friends of Aurora Team: Please, excuse me for adding more questions to the subject of NLA. In the previous email I pointed out the difference between the NLA final displacement (136 mm) and that of the LA (199 MM). In other words, the output the NLA was found to be 68.3% of the output of the LA. Giv...

Re: Non Linear Analysis - Hinge example

Estimated Mr. Fisch As you point out, and as I understand it, for small displacements, the projected load variation (either by the angular variation of the application area or by its distance to the position constraints) is not enough to be relevant, so the displacement progression appears to be lin...

Re: Non Linear Analysis - Hinge example

Felix, thank you very much for your answer. I'm not really "worried" about the runtime, but I'm still confused about some other subjects related to the outputs of this case. I observed that if a Linear Analysis is applied to the same model and BCs, the total displacement results are the sa...

Non Linear Analysis - Hinge example

Good day Aurora Team I tried the Hinge example in order to learn how to manage Non Linear Analysis. I believe I correctly followed the instructions and applied the indicated model, mesh, BCs. etc. Finally I think I got the same results of the guide. But... The guide points that the elapsed time for ...
