I received an error when I tried to compact my Comsol file

Syntax error in expression
- Expression: SpaceCharge(root.x[[um]],root.y[[um]])
- Subexpression: [[um]],root
- Position: 19

I cannot understand where the error is coming from. SpaceCharge is an interpolation function.

Hi John, the problem seems to be with the disabled "2DPlot Group 1" feature under Results. In the "Surface 1" plot, the expression is set to SpaceCharge(root.x[[um]],root.y[[um]]). COMSOL can't interpret the double square brackets when compacting history. To fix the problem, simply replace the expression with SpaceCharge(root.x[um],root.y[um]). You should be able to compact history after making this change.
