N- are the positive and negative nodes, respectively. If specified, ND is the number of dimensions, which must be positive. One pair of nodes must be specified for each dimension. Pn are the polynomial coefficients. If not specified, 0.0 is assumed.
Current flow is from the positive node, through the source, to the negative node.
If specified, ND is the number of dimensions, which must be positive. The direction of positive controlling current flow is from the positive node, through the source, to the negative node of each voltage source. Pn are the polynomial coefficients. If not specified, 0.0 is assumed. If specified, ND is the number of dimensions, which must be positive.
