I am trying to run a structure in PropCalc and get too many subsections and unknowns to run. What do I do?
Because the grid along each direction must be uniform, the facility in the GUI tries to find a commensurate grid size, for each direction, among all the shapes. The user may need to slightly adjust the dimensions of some shapes so that a reasonable value of grid size can represent the entire structure. For example, if conductors having widths along the y direction are 0.100 mm and 0.205 mm and their spacing is 0.54 mm, the user could use widths of 0.100 mm and 0.200 mm and change the spacing to 0.55 mm, so that a grid of 0.05 mm could be used instead. The GUI will try to find a commensurate grid, but this grid may be too fine (requiring too many unknowns or exceeding the internal limit of 1000 along any direction). In such cases, the user must modify the structure as just described.
