force_limits/combination_matrix(:,:) ⇹-FLT_2D¶Force limits are expressed as a linear combination of the forces […]
Force limits are expressed as a linear combination of the forces on each individual coil. The weights of the linear combination are given by this matrix, while the limits are given by the sibling nodes limit_min and limit_max. Each row of this matrix corresponds to a force limit. The columns represent, for each coil, the 4 types of forces on the coil namely [coil1_radial, coil1_vertical, coil1_radial_crush, coil1_vertical_crush, coil2_radial, coil2_vertical, coil2_radial_crush, coil2_vertical_crush, …]. There are therefore 4*coils_n columns.

circuit(i1)/connections(:,:)INT_2D¶Description of the supplies and coils connections (nodes) across […]
Description of the supplies and coils connections (nodes) across the circuit. Nodes of the circuit are listed as the first dimension of the matrix. Supplies (listed first) and coils (listed second) SIDES are listed as the second dimension. Thus the second dimension has a size equal to 2*(N_supplies+N_coils). N_supplies (resp. N_coils) is the total number of supplies (resp. coils) listed in the supply (resp.coil) array of structure, i.e. including also supplies/coils that are not part of the actual circuit. The (i,j) matrix elements are 1 if the j-th supply or coil side is connected to the i-th node, or 0 otherwise. For coils, sides are listed so that a current flowing from side 1 to side 2 (inside the coil) is positive (i.e. counter-clockwise when seen from above).
