Confusion with the DirectIntegrationAnalysis::domainChanged

[yaqiang.jiang]

Dear Frank,

I've got problems with two statements inside the body of DirectIntegrationAnalysis::domainChanged() :

theDOF_Numberer->numberDOF();
theConstraintHandler->doneNumberingDOF();


The two are invoked sequentially and both of them invoke the method FE_Element::setID() to assign equation numbers to all the dofs.What I got confused with is, the numberDOF() has already done the job,why do we still need the doneNumberingDOF there?

Thanks in Advance

one of the constraint handlers needs the info .. i think is is the transformation handler .. look at the source code for the handlers to see which.
