I thought the existing implementation was crystal clear on this point. :-) I think the following rules should apply: 1. TestSpace should be added when the rank of the form is >= 1 2. TrialSpace should be added when the rank of the form is >= 2 3. FunctionSpace should be added if all the first r spaces are the same (4. CoefficientSpace should be added if the n coefficient space are the same) So for a regular Poisson's equation, we could have TestSpace TrialSpace FunctionSpace CoefficientSpace -- Anders _______________________________________________ Mailing list: https://launchpad.net/~dolfin Post to : dolfin@lists.launchpad.net Unsubscribe : https://launchpad.net/~dolfin More help : https://help.launchpad.net/ListHelp
