fix isBdNode not assigned a value bug #12

Closed litaihe closed 8 months ago

litaihe commented 8 months ago

when I run the example\fem\Maxwell\Maxwell3ND0femrate.m, the fellowing error will appear

Output argument "isBdNode" (and possibly others) not assigned a value in
the execution with "gradmatrix" function.

Error in mgMaxwell (line 79)
[grad,isBdNode] = gradmatrix(edge,isBdEdge);

Error in Maxwell (line 393)
    [u,info] = mgMaxwell(bigAD,f,AP,node,elemold,edge,HB,option);

Error in femMaxwell3 (line 60)
                [u,edge,eqn,info] = Maxwell(node,elem,bdFlag,pde,option);

Error in Maxwell3ND0femrate (line 39)
femMaxwell3(mesh,pde,option);

this error will be resolved when I make the following changes to the file solver/gradmatrix.m
