    "Goal Driven Optimization" sensitivity in ANSYS

    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...

    Quick question on midside nodes

    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...

    Best way to connect volumes? (or: how to convert 4 to 10 node tets?)

    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...

    determining residual strain

    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...

    Selecting interior surface only of enclosed region

    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...
