Comparing Results Between Models

Comparing results between models

It is possible to derive results in one model with respect to another - essentially by subtracting data in Model B from that in Model A. This is done in the DEFORM, REFERENCE STATE/MODEL panel. Briefly:

• You can plot data and coordinates relative to a state in the current model.
• You can also plot relative to a state (or the current state) in a different "reference" model.

For example you can plot the difference between two analyses where you have changed a section property, or remeshed an area.

Data is compared using labels, for example the data for node 100 in Model B is subtracted from that for node 100 in Model A. Therefore the models need not be identical, but they do need to be topologically similar for this to work. In particular comparisons in regions which have been remeshed are likely to be unsatisfactory.

In future releases we hope to perform "geographically" based comparison, where the node or element in Model B nearest to that in Model A is used, removing the dependency upon identical labels.
