Description

FINDBDR Find boundary indices for an expression.

[ BDR, INDB ] = FINDBDR( SIN, S_EXPR, MATCH_ALL ) Evaluates S_EXPR for boundary nodes in the grid or fea struct and returns the boundary numbers BDR for which the expression is true, and also indices to the corresponding boundary segments (columns in grid.b). The flag MATCH_ALL requires all nodes on a boundary to fulfill S_EXPR.

Required fields of sin:
