Visualization of difference between solutions

Hi there
I have a model with 4 different solutions stored. Theese solutions are aquired in the same geomtry but with different meshes and boundary conditions. I would like to compare the results from theese different studyies and visualize them.
I am modelling fluid flow so it would be natural to compare the velocities, is there an easy way to plot, for instance, the difference in velocity from two solutions? something like a sliceplot of [(solution1 spf.U) - (solution2 spf.U)] would be perfect.
As far as I can see, when I choose the velocity node under results I have to choose only one of the stored solutions.
Thanks in advance for your help
Best regards

Hi,
In version 4.2a you can create Join data sets that combine two solutions. The default is to form the difference (but you can also form a sum, product, quotient, or general expression). You can then point to such a Join data set from a plot group to visualize the difference between the solutions.
