ANSYS: melting using element death--how to transfer convection BC from deactivated elements?
Submitted by bumblebee on Thu, 2008-10-30 14:14.I am modelling melting by element death. I have a cold (melting) rectangle with a hot fluid convecting at the exterior. I am using a do loop so that time increases at each loop. I define a "melting" temperature, so that elements are killed off when they achieve a specified temperature.
The problem I'm having is that I'm getting this error: "Surface loads on line x are not transferred to unselected element y". I think this means that the convection boundary conditions are not being transferred from the exterior, deactivated/killed elements to the active (not yet melted) ones. Does anyone know how to deal with this?
ANSYS ANIMATION problem: how can I animate the results of a loop (of element death over time)?
Submitted by bumblebee on Tue, 2008-10-21 16:39.I previously posted asking for help with writing command line code to model melting via element death over time. Biswajit kindly helped me write a loop to kill off any "melted" elements. Now I would like to animate the results. I would be very grateful for any suggestions on how to save results from the loop calculations and then animate them. My aim is to get an animation that shows temperature contours evolving as well as elements disappearing as they achieve a specified temperature. I am a new user and would find detailed suggestions most helpful.
The code I have so far (up to the animation step) is below. Thanks...
ANSYS qu from new user: help me write a "for" loop please!
Submitted by bumblebee on Sat, 2008-10-18 17:31.Hi: I am a new ANSYS user and would really appreciate help writing a "for"-type loop to go with an example found here:
http://www.mece.ualberta.ca/tutorials/ansys/CL/CAT/BirthDeath/Print.html
At the end of the example is the paragraph below. I want to know how to do this! Can anyone modify the code for me? I don't even know where to start. I would be very grateful!
