Ok, so just as I posted this I finally found mention that it is somehow based on the Spearman rank correlation coefficient, although it still does not really explain how this is extended n-dimensionally. Any further insight or references would still be very welcome.
Hello,
I'm doing a little project involving Design of Experiments in ANSYS (DesignXplorer). I've noticed that I can calculate a supposed "global" sensitivity to each design factor based on the "Goal Driven Optimization" technique in the program. It does not, however, provide any reference...
I've gotten myself into a self-doubting circle of logic, so am hoping someone can quickly set me right. I'm currently working with SOLID92 tetrahedral elements, which have four corner nodes and six midside nodes. I'd like to apply a surface load (i.e. a pressure) to these nodes. I remember...
I've unfortunately tried using NUMMRG already with no results. It says that there are no coincident keypoints to merge. I assume this is the case because the original four node tetrahedrons already have shared nodes at their boundaries. However, in ANSYS this translates to me having 35,000...
Hello and thanks for your quick reply,
I had thought along similar lines, but as far as I know there is no way to create the midside nodes in my triangles that would be necessary to create a 10 node tetrahedral from my four node data. As far as I know, ANSYS is not capable of creating midside...
Hello,
I'm working on a MATLAB script that transforms data from an MRI scanner to an APDL script for analysis in ANSYS. From the MRI data I get nodes and connectivity for four node tetrahedrons. Unfortunately, however, there is no connectivity between these volumes: the only data I get is...
Hi cbrn,
Thanks for another very informative post.
It's unfortunate that you've confirmed what I suspected--that doing this won't be at all easy.
Unfortunately, external services likely aren't an option to me as I work with an academic research group affiliated with a hospital rather than...
I was thinking something along similar lines, but wondered why no one else seemed to do it. Now I know. Exactly numbering things will definitely be difficult.
Perhaps what I should do is start with three meshes: the two meshes that I already have from the data, and a third idealized mesh...
The above poster is right. Setting components is the easiest way to name a volume. If you are having trouble actually finding the volume to name, you have a few options. First of all, in the GUI you can turn on volume numbering in the PlotCtrls menu. You can use the VLIST command to list...
Hello,
This is more of a general theory question rather than a technical one. I have full 3D data (to be specific, MRI scans) of a piece of tissue both in situ and after it has been cut away. Cutting away the tissue relieves any residual strain left in it, causing a deformation of the tissue...
I currently am using SOLID45 tetrahedral elements, as the MRI meshes are tetrahedral when outputted. As far as I know, there's no easy way to move over to shell from this, correct?
Mihaiupb, that's kind of what I'm thinking at this point too. Unfortunately real human eyes aren't exactly...
Hello,
I've lurked here for a while, but finally signed up to ask a question. I'm not sure if it's easy/hard/impossible, but I seem to be stumped with a relatively simple problem:
I'm modeling the tissue of an eye in ANSYS using a mesh generated from MRI data (therefore no mapped meshing). I...
