The mesh contains negative elements
WebThe Mesh Current Method described next works on planar circuits (circuits that can be drawn flat, without crossing wires). Most of the circuits you will come across will be planar. If the circuit is non-planar (can only be drawn with crossing wires), there is a small modification to the method, and it gets the name Loop Current Method. Most of the … WebIf the mesh contains negative Jacobians and this command is issued, Cubit automatically calls the Untangle smoother and attempts to remove the negative Jacobians. If successful, condition number smoothing occurs next; the resulting mesh should have no negative Jacobians. If untangling is unsuccessful, condition number smoothing is not performed.

WebLoop – A loop is any closed path going through circuit elements. To draw a loop, select any node as a starting point and draw a path through elements and nodes until the path comes back to the node where you started. There is only one rule: a loop can visit (pass through) a node only one time. It is ok if loops overlap or contain other loops.
