Hi all,
In the 2d magnetostatics a example: I'd like to view
B-normal on a 1-d contour in the 2-d Domain. Viewing
{a} on the contour (called 'Ubound') is easy:
{ Name boundary_a ; Value { Local { [ {a} ] ;
In Ubound ; Jacobian MyJac ; } } }
Works fine, but
{ Name boundary_b ; Value { Local { [ {d a} ] ;
In Ubound ; Jacobian MyJac ; } } }
throws
Error : Null determinant in 'ChangeOfCoord_Form2P'
UAny help would be gatefully appreciated.
All the best
