Hi,

I have a question puzzled me for a while. It is about the moving mesh problem. I need to model the shrinkage phenomena during mass and heat transfer. I applied moving mesh. But my problem is that I can only see the final result and I can not compare with the original position. I would like to know whether someone can guide me to this problem. I would like to make the original position visible as well. Thanks.

Xin

hi,
Please make your model time dependent, so that you will be able to different transition states of your model.

Look at deformed shape plot in post-processing.

something like this should show you both the deformed shape and also the original shape:

Hi,

I don't know if I got your point !!
But it seems that you want to see the initial boundary of your geometry after the end of your calculation.
You can select "geometry edges" in plot parameters. This will keep the initial boundary in the plotted solution. This can help you to see the difference between the initial and the final positions of your moving boundaries.

I hope it helps

Ciao

Hi there, iam trying to model ALE transient system in 3D as I attached the file, I was wondering if you cna help me to find out how can I fix the "shape function" problem with my file.

"s" [as I guess] is the shape function for 2D simulation, but for 3D modeling, I tried the same rules and it face to error.
would you please have a look at my files?
Best and thank you in advance
