Thanks disla !
I had used the data remote from the instability for the analysis I was doing.
I can see the improvement in the models and step sizes you used.
Thanks for your help.
Thanks Victor.
When changing to just 2D node output, the results matched the named nodes.
Hi disla, I understand the mesh aspect ratio is high, and I don't really need that large a model for the, essentially 1D phenomena I am trying to model.
I wil…
I have attached some pictures of the node numbers selected in "Profile" selection and the actual node numbers for the Tabular results.
These are located at different points in the model.
Perhaps the Names Selection needs to be updated for model refi…
I have designed the equivalent 2D model, with similar instabiltiy.
Refining the mesh helped a little, and I don't think the minor instability will affect the overall result.
I do have another issue, though.
I want results for selected nodes, and I …
Thanks for your input and comment.
I will try a 2D cross-section first.
I am getting quite good correlation between my 1-D FD model and the FEA model, so I have no problem with accuracy etc., but I would like to see the transient.
I'll let you know …
