Simulation is pretty *cool* but how *cool* is it really?
Back in 2024 I presented a little introduction to simulation at PyCon. Introduction to Simulation And in that presentation I asked a fundamental physics question. If a heavy cat sits on a bridge of ice. Does that bridge break? But in that situation everything was simply two dimensional (to save time). But what if it…

Erroneous Node Scoping Output from Base Sector Cyclic Expansion
I am performing cyclic expansion on a von Mises stress result for a single stage cyclic symmetric model via DPF. I first get the real and imaginary stress results, then supply those as inputs to the cyclic expansion. I want to expand results only for the base sector. However, I find that when I access the cyclic expanded…

Issue with mapping.on_coordinates operator
I am using dpf.core to facilitate the post process of simulation for the nuclear domain. I have developed some python code to create objects like node and segment where I want to map the nodal stress. Getting the stress tensor on segments allows me to linearize the stress in a python environment which can be then used in a…

Question on adding a custom property to a joint/Adding additional control to a user object
Hey all, I am trying to automate adding joints to my simulation. I already succeeded in adding them via the scripting interface in Mechanical but I feel there are some drawbacks to my solution: * right now, the properties of the joint are defined by the parents name of where my mobile named reference is. This could lead to…

Ansys Equivalent Von Mises Stress Plot through PyPDF-core
I have an Ansys Mechanical static structural model in which I have plotted the equivalent stress (Von Mises). I've read this model into python using the PyDPF-core library and am attempting to generate the same plot as in Ansys No matter which route I take, I never seem to get a plot that aligns. I've used…
